As explained in [0] currently we may leave SMBHSTSTS_INUSE_STS set,
thus potentially breaking ACPI/BIOS usage of the SMBUS device.
Seems patch [0] needs a little bit more of review effort, therefore
I'd suggest to apply a part of it as quick win. Just clearing
SMBHSTSTS_INUSE_STS when leaving i801_access() should fix the
referenced issue and leaves more time for discussing a more
sophisticated locking handling.

Pull SCSI fixes from James Bottomley:
"Four reasonably small fixes to the core for scsi host allocation

The root problem is that we're not freeing the memory allocated by

paths to do put_device() instead of kfree which, in turn, has several
other knock on ramifications and inspection turned up a few other

Pull USB fixes from Greg KH:
"Here are a number of tiny USB fixes for 5.13-rc6.
There are more than I would normally like, but there's been a bunch of
people banging on the gadget and dwc3 and typec code recently for I
think an Android release, which has resulted in a number of small
fixes. It's nice to see companies send fixes upstream for this type of
work, a notable change from years ago.
Anyway, fixes in here are:
- usb-serial device id updates
- usb-serial cp210x driver fixes for broken firmware versions
- typec fixes for crazy charging devices and other reported problems
- dwc3 fixes for reported problems found
- gadget fixes for reported problems
- tiny xhci fixes

Commit c76f48eb5c08 ("block: take bd_mutex around delete_partitions in
del_gendisk") adds disk->part0->bd_mutex in del_gendisk(), this way
causes the following AB/BA deadlock between removing loop and opening
loop:
1) loop_control_ioctl(LOOP_CTL_REMOVE)
-> mutex_lock(&loop_ctl_mutex)
-> del_gendisk
-> mutex_lock(&disk->part0->bd_mutex)
2) blkdev_get_by_dev
-> mutex_lock(&disk->part0->bd_mutex)
-> lo_open
-> mutex_lock(&loop_ctl_mutex)
Add a new Lo_deleting state to remove the need for clearing
->private_data and thus holding loop_ctl_mutex in the ioctl
LOOP_CTL_REMOVE path.
Based on an analysis and earlier patch from
Ming Lei <ming.lei@redhat.com>.

If ucsi_init() fails for some reason (e.g. ucsi_register_port()
fails or general communication failure to the PPM), particularly at
any point after the GET_CAPABILITY command had been issued, this
results in unwinding the initialization and returning an error.
However the ucsi structure's ucsi_capability member retains its
current value, including likely a non-zero num_connectors.
And because ucsi_init() itself is done in a workqueue a UCSI
interface driver will be unaware that it failed and may think the
ucsi_register() call was completely successful. Later, if
ucsi_unregister() is called, due to this stale ucsi->cap value it
would try to access the items in the ucsi->connector array which
might not be in a proper state or not even allocated at all and
results in NULL or invalid pointer dereference.
Fix this by clearing the ucsi->cap value to 0 during the error
path of ucsi_init() in order to prevent a later ucsi_unregister()
from entering the connector cleanup loop.

The commit a390bef7db1f ("usb: gadget: fsl_mxc_udc: Remove the driver")
dropped the ARCH_MXC dependency from USB_FSL_USB2, leaving it depending
solely on FSL_SOC.
FSL_SOC is powerpc only; it was briefly available on ARM in 2014 but was
removed by commit cfd074ad8600 ("ARM: imx: temporarily remove
CONFIG_SOC_FSL from LS1021A"). Therefore the driver can no longer be
enabled on ARM platforms.
This appears to be a mistake as arm64's ARCH_LAYERSCAPE and arm32
SOC_LS1021A SoCs use this symbol. It's enabled in these defconfigs:
arch/arm/configs/imx_v6_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/arm/configs/multi_v7_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mgcoge_defconfig:CONFIG_USB_FSL_USB2=y
arch/powerpc/configs/mpc512x_defconfig:CONFIG_USB_FSL_USB2=y
To fix, expand the dependencies so USB_FSL_USB2 can be enabled on the
ARM platforms, and with COMPILE_TEST.

TPS23861 has a configuration bit for setting of the
current shunt value used on the board.
Its bit 0 of the General Mask 1 register.
According to the datasheet bit values are:
0 for 255 mOhm (Default)
1 for 250 mOhm
So, configure the bit before registering the hwmon
device according to the value passed in the DTS or
default one if none is passed.
This caused potentially reading slightly skewed values
due to max current value being 1.02A when 250mOhm shunt
is used instead of 1.0A when 255mOhm is used.

CP2102N revision A01 (firmware version <= 1.0.4) has a buggy
flow-control implementation that uses the ulXonLimit instead of
ulFlowReplace field of the flow-control settings structure (erratum
CP2102N_E104).
A recent change that set the input software flow-control limits
incidentally broke RTS control for these devices when CRTSCTS is not set
as the new limits would always enable hardware flow control.
Fix this by explicitly disabling flow control for the buggy firmware
versions and only updating the input software flow-control limits when
IXOFF is requested. This makes sure that the terminal settings matches

A problem was reported on CoachZ devices where the display wouldn't come
up, or it would be distorted. It turns out that the PLL code here wasn't
getting called once dsi_pll_10nm_vco_recalc_rate() started returning the
same exact frequency, down to the Hz, that the bootloader was setting
instead of 0 when the clk was registered with the clk framework.
After commit 001d8dc33875 ("drm/msm/dsi: remove temp data from global
pll structure") we use a hardcoded value for the parent clk frequency,
i.e. VCO_REF_CLK_RATE, and we also hardcode the value for FRAC_BITS,
instead of getting it from the config structure. This combination of
changes to the recalc function allows us to properly calculate the
frequency of the PLL regardless of whether or not the PLL has been
clk_prepare()d or clk_set_rate()d. That's a good improvement.
Unfortunately, this means that now we won't call down into the PLL clk
driver when we call clk_set_rate() because the frequency calculated in
the framework matches the frequency that is set in hardware. If the rate
is the same as what we want it should be OK to not call the set_rate PLL
op. The real problem is that the prepare op in this driver uses a
private struct member to stash away the vco frequency so that it can
call the set_rate op directly during prepare. Once the set_rate op is
never called because recalc_rate told us the rate is the same, we don't
set this private struct member before the prepare op runs, so we try to
call the set_rate function directly with a frequency of 0. This
effectively kills the PLL and configures it for a rate that won't work.
Calling set_rate from prepare is really quite bad and will confuse any
downstream clks about what the rate actually is of their parent. Fixing
that will be a rather large change though so we leave that to later.
For now, let's stash away the rate we calculate during recalc so that
the prepare op knows what frequency to set, instead of 0. This way
things keep working and the display can enable the PLL properly. In the
future, we should remove that code from the prepare op so that it
doesn't even try to call the set rate function.

The function init_cq_frag_buf() can be called to initialize the current CQ
fragments buffer cq->buf, or the temporary cq->resize_buf that is filled
during CQ resize operation.
However, the offending commit started to use function get_cqe() for
getting the CQEs, the issue with this change is that get_cqe() always
returns CQEs from cq->buf, which leads us to initialize the wrong buffer,
and in case of enlarging the CQ we try to access elements beyond the size
of the current cq->buf and eventually hit a kernel panic.

This patch eliminates the following smatch warning:
drivers/gpu/drm/drm_auth.c:320 drm_master_release() warn: unlocked access 'master' (line 318) expected lock '&dev->master_mutex'
The 'file_priv->master' field should be protected by the mutex lock to
'&dev->master_mutex'. This is because other processes can concurrently
modify this field and free the current 'file_priv->master'
pointer. This could result in a use-after-free error when 'master' is
dereferenced in subsequent function calls to
'drm_legacy_lock_master_cleanup()' or to 'drm_lease_revoke()'.
An example of a scenario that would produce this error can be seen
from a similar bug in 'drm_getunique()' that was reported by Syzbot:
https://syzkaller.appspot.com/bug?id=148d2f1dfac64af52ffd27b661981a540724f803
In the Syzbot report, another process concurrently acquired the
device's master mutex in 'drm_setmaster_ioctl()', then overwrote
'fpriv->master' in 'drm_new_set_master()'. The old value of
'fpriv->master' was subsequently freed before the mutex was unlocked.

This patch fixes crash after resuming from hibernation. The issue
occurs when mhi stack is builtin and so part of the 'restore-kernel',
causing the device to be resumed from 'restored kernel' with a no
more valid context (memory mappings etc...) and leading to spurious
crashes.
This patch fixes the issue by implementing proper freeze/restore

This driver's remove path calls del_timer(). However, that function
does not wait until the timer handler finishes. This means that the
timer handler may still be running after the driver's remove function
has finished, which would result in a use-after-free.
Fix by calling del_timer_sync(), which makes sure the timer handler
has finished, and unable to re-schedule itself.

Commit 719e1f561afb ("ACPI: Execute platform _OSC also with query bit
clear") makes acpi_bus_osc_negotiate_platform_control() not only query
the platforms capabilities but it also commits the result back to the
firmware to report which capabilities are supported by the OS back to
the firmware
On certain systems the BIOS loads SSDT tables dynamically based on the
capabilities the OS claims to support. However, on these systems the
_OSC actually clears some of the bits (under certain conditions) so what
happens is that now when we call the _OSC twice the second time we pass
the cleared values and that results errors like below to appear on the
system log:
ACPI BIOS Error (bug): Could not resolve symbol [\_PR.PR00._CPC], AE_NOT_FOUND (20210105/psargs-330)
ACPI Error: Aborting method \_PR.PR01._CPC due to previous error (AE_NOT_FOUND) (20210105/psparse-529)
In addition the ACPI 6.4 spec says following [1]:
If the OS declares support of a feature in the Support Field in one
call to _OSC, then it must preserve the set state of that bit
(declaring support for that feature) in all subsequent calls.
Based on the above we can fix the issue by passing the same set of
capabilities to the platform wide _OSC in both calls regardless of the
query flag.
While there drop the context.ret.length checks which were wrong to begin
with (as the length is number of bytes not elements). This is already
checked in acpi_run_osc() that also returns an error in that case.
Includes fixes by Hans de Goede.

The calclulation of how many bytes we stuff into the
DSI pipeline for video mode panels is off by three
orders of magnitude because we did not account for the
fact that the DRM mode clock is in kilohertz rather
than hertz.
This used to be:
drm_mode_vrefresh(mode) * mode->htotal * mode->vtotal
which would become for example for s6e63m0:
60 x 514 x 831 = 25628040 Hz, but mode->clock is
25628 as it is in kHz.
This affects only the Samsung GT-I8190 "Golden" phone
right now since it is the only MCDE device with a video
mode display.
Curiously some specimen work with this code and wild
settings in the EOL and empty packets at the end of the
display, but I have noticed an eeire flicker until now.
Others were not so lucky and got black screens.
