The syzbot fuzzer provoked a general protection fault in the
hid-prodikeys driver:

The problem is caused by the fact that pcmidi_get_output_report() will
return an error if the HID device doesn't provide the right sort of
output report, but pcmidi_set_operational() doesn't bother to check
the return code and assumes the function call always succeeds.
This patch adds the missing check and aborts the probe operation if
necessary.

The sony driver is not properly cleaning up from potential failures in
sony_input_configured. Currently it calls hid_hw_stop, while hid_connect
is still running. This is not a good idea, instead hid_hw_stop should
be moved to sony_probe. Similar changes were recently made to Logitech
drivers, which were also doing improper cleanup.

This 'SET_PWR_WAKEUP_DEV' quirk only works for weida's devices with pid
0xC300 & 0xC301. Some weida's devices with other pids also need this quirk
now. Use 'HID_ANY_ID' instead of 0xC300 to make all of weida's devices can be
fixed on the power on issue. This modification should be safe since devices
without power on issue will send the power on command only once.

Before this commit dj_probe would exit with an error if the initial
logi_dj_recv_query_paired_devices fails. The initial call may fail
when the receiver is connected through a kvm and the focus is away.
When the call fails this causes 2 problems:
1) dj_probe calls logi_dj_recv_query_paired_devices after calling
hid_device_io_start() so a HID report may have been received in between
and our delayedwork_callback may be running. It seems that the initial
logi_dj_recv_query_paired_devices failure happening with some KVMs triggers
this exact scenario, causing the work-queue to run on free-ed memory,
leading to:

2) Even if we were to fix 1. by making sure the work is stopped before
failing probe, failing probe is the wrong thing to do, we have
logi_dj_recv_queue_unknown_work to deal with the initial
logi_dj_recv_query_paired_devices failure.
Rather then error-ing out of the probe, causing the receiver to not work at
all we should rely on this, so that the attached devices will get properly
enumerated once the KVM focus is switched back.

It turns out the fault was caused by a bug in the HID Logitech driver,
which violates the requirement that every pathway calling
hid_hw_start() must also call hid_hw_stop(). This patch fixes the bug
by making sure the requirement is met.

When calling request_threaded_irq() with a CP2112, the function
cp2112_gpio_irq_startup() is called in a IRQ context.
Therefore we can not sleep, and we can not call
cp2112_gpio_direction_input() there.
Move the call to cp2112_gpio_direction_input() earlier to have a working
driver.

when plugging it in, the driver tries to contact it but it fails.
This timeout is problematic as it introduce a delay in the boot,
and having only the mouse event node means that the hardware

This partially reverts commit 27fc32fd9417968a459d43d9a7c50fd423d53eb9.
It turns out that the G502 has some issues with hid-logitech-hidpp:
when plugging it in, the driver tries to contact it but it fails.
So the driver bails out leaving only the mouse event node available.
This timeout is problematic as it introduce a delay in the boot,

Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4
gamepad while rumble is enabled. This issue is reproducible with a
frequency of 1 in 3 times in the game Borderlands 2 when using an
automatic weapon, which triggers many rumble operations.
We found the issue to be a race condition between sony_remove and the
final device destruction by the HID / input system. The problem was
that sony_remove didn't clean some of its work_item state in
"struct sony_sc". After sony_remove work, the corresponding evdev
node was around for sufficient time for applications to still queue
rumble work after "sony_remove".
On pre-4.19 kernels the race condition caused a kernel crash due to a
NULL-pointer dereference as "sc->output_report_dmabuf" got freed during
sony_remove. On newer kernels this crash doesn't happen due the buffer
now being allocated using devm_kzalloc. However we can still queue work,
while the driver is an undefined state.
This patch fixes the described problem, by guarding the work_item
"state_worker" with an initialized variable, which we are setting back
to 0 on cleanup.

Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
the previous wheel report was horizontal or vertical. Before
c01908a14bf73 ("HID: input: add mapping for "Toggle Display" key") this
usage was being mapped to 'Relative.Misc'. After the patch it's simply
ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
usage->type.
We shouldn't rely on a mapping for that usage as it's nonstandard and
doesn't really map to an input event. So we bypass the mapping and make
sure the custom event handling properly handles both reports.

The Saitek X52 joystick has a pair of axes that are originally
(by the Windows driver) used as mouse pointer controls. The corresponding
usage->hid values are 0x50024 and 0x50026. Thus they are handled
as unknown axes and both get mapped to ABS_MISC. The quirk makes
the second axis to be mapped to ABS_MISC1 and thus made available
separately.

Commit dbcbabf7da92 ("HID: logitech-dj: fix return value of
logi_dj_recv_query_hidpp_devices") made logi_dj_recv_query_hidpp_devices
return the return value of hid_hw_raw_request instead of unconditionally
returning 0.
But hid_hw_raw_request returns the report-size on a successful request
(and a negative error-code on failure) where as the callers of
logi_dj_recv_query_hidpp_devices expect a 0 return on success.
This commit fixes things so that either the negative error gets returned
or 0 on success, fixing HID++ receivers such as the Logitech nano receivers
no longer working.

The nr_allocated_banks and allocated banks are initialized as part of
tpm_chip_register. Currently, this is done as part of auto startup
function. However, some drivers, like the ibm vtpm driver, do not run
auto startup during initialization. This results in uninitialized memory
issue and causes a kernel panic during boot.
This patch moves the pcr allocation outside the auto startup function
into tpm_chip_register. This ensures that allocated banks are initialized
in any case.

Let's document why the lock is not needed in acpi_scan_init(), right now
this is not really obvious.

Pull more drm fixes from Daniel Vetter:
"Dave sends his pull, everyone realizes they've been asleep at the
wheel and hits send on their own pulls :-/
Normally I'd just ignore these all because w/e for me and Dave. But
this time around the latecomers also included drm-intel-fixes, which
failed to send out a -fixes pull thus far for this release (screwed up
vacation coverage, despite that 2/3 maintainers were around ... they
all look appropriately guilty), and that really is overdue to get
landed.
And since I had to do a pull request anyway I pulled the other two
late ones too.
intel fixes (didn't have any ever since the main merge window pull):
- gvt fixes (2 cc: stable)
- fix gpu reset vs mm-shrinker vs wakeup fun (needed a few patches)
- two gem locking fixes (one cc: stable)
- pile of misc fixes all over with minor impact, 6 cc: stable, others
from this window
exynos:
- misc minor fixes
misc:
- some build/Kconfig fixes
- regression fix for vm scalability perf test which seems to mostly
exercise dmesg/console logging ...
- the vgem cache flush fix for arm64 broke the world on x86, so
that's reverted again

On x86_64, when CONFIG_OF is not disabled:
WARNING: unmet direct dependencies detected for MUX_MMIO

Selected by [y]:

Fix this by making HBMC_AM654 imply MUX_MMIO instead of select so
that dependencies are taken care of. MUX_MMIO is optional for
functioning of driver.

Some devices are not supposed to support on-die ECC but experience
shows that internal ECC machinery can actually be enabled through the
"SET FEATURE (EFh)" command, even if a read of the "READ ID Parameter
Tables" returns that it is not.
Currently, the driver checks the "READ ID Parameter" field directly
after having enabled the feature. If the check fails it returns
immediately but leaves the ECC on. When using buggy chips like
MT29F2G08ABAGA and MT29F2G08ABBGA, all future read/program cycles will
go through the on-die ECC, confusing the host controller which is
supposed to be the one handling correction.
To address this in a common way we need to turn off the on-die ECC
directly after reading the "READ ID Parameter" and before checking the
"ECC status".

cleanups, but they simplify and fix the odd fc_rport_priv structure
handling rules so that the new gcc-9 warnings about memset crossing
structure boundaries are gone.
The old code was hard for humans to understand too, and really
