Pull power management fixes from Rafael Wysocki:
"These add a check to avoid recent suspend-to-idle power regression on
systems with NVMe drives where the PCIe ASPM policy is "performance"
(or when the kernel is built without ASPM support), fix an issue
related to frequency limits in the schedutil cpufreq governor and fix
a mistake related to the PM QoS usage in the cpufreq core introduced
recently.
Specifics:
- Disable NVMe power optimization related to suspend-to-idle added
recently on systems where PCIe ASPM is not able to put PCIe links
into low-power states to prevent excess power from being drawn by
the system while suspended (Rafael Wysocki).
- Make the schedutil governor handle frequency limits changes
properly in all cases (Viresh Kumar).
- Prevent the cpufreq core from treating positive values returned by
dev_pm_qos_update_request() as errors (Viresh Kumar)"

when CONFIG_HAS_IOMEM is set/enabled, so XILINX_SDFEC should depend

The USB buffer allocation code is the only place in the usb core (and in
fact the whole kernel) that uses is_device_dma_capable, while the URB
mapping code uses the uses_dma flag in struct usb_bus. Switch the buffer
allocation to use the uses_dma flag used by the rest of the USB code,
and create a helper in hcd.h that checks this flag as well as the
CONFIG_HAS_DMA to simplify the caller a bit.

If driver probe needs to be deferred, e.g. because ci_hdrc_add_device()
isn't ready yet, this driver currently misbehaves badly:
a) success is still reported to the driver core (meaning a 2nd
probe attempt will never be done), leaving the driver in
a dysfunctional state and the hardware unusable
b) driver remove / shutdown OOPSes:

c) the error path in combination with driver removal causes
imbalanced calls to the clk_*() and pm_()* APIs
a) happens because the original intended return value is
overwritten (with 0) by the return code of
regulator_disable() in ci_hdrc_imx_probe()'s error path
b) happens because ci_pdev is -EPROBE_DEFER, which causes
ci_hdrc_remove_device() to OOPS
Fix a) by being more careful in ci_hdrc_imx_probe()'s error
path and not overwriting the real error code
Fix b) by calling the respective cleanup functions during
remove only when needed (when ci_pdev != NULL, i.e. when
everything was initialised correctly). This also has the
side effect of not causing imbalanced clk_*() and pm_*()
API calls as part of the error code path.

Previously, EROFS uses EIO to indicate that filesystem

let's follow what others do right now.
Also, add some more prints to the syslog.

On Motorola Mapphone devices such as Droid 4 there are five USB ports
that do not use the same layout as Gobi 1K/2K/etc devices listed in
qcserial.c. So we should use qcaux.c or option.c as noted by
Dan Williams <dan.j.williams@intel.com>.
As the Motorola USB serial ports have an interrupt endpoint as shown
with lsusb -v, we should use option.c instead of qcaux.c as pointed out
by Johan Hovold <johan@kernel.org>.
The ff/ff/ff interfaces seem to always be UARTs on Motorola devices.
For the other interfaces, class 0x0a (CDC Data) should not in general
be added as they are typically part of a multi-interface function as
noted earlier by Bjørn Mork <bjorn@mork.no>.
However, looking at the Motorola mapphone kernel code, the mdm6600 0x0a
class is only used for flashing the modem firmware, and there are no
other interfaces. So I've added that too with more details below as it
works just fine.
The ttyUSB ports on Droid 4 are:
ttyUSB0 DIAG, CQDM-capable
ttyUSB1 MUX or NMEA, no response
ttyUSB2 MUX or NMEA, no response
ttyUSB3 TCMD
ttyUSB4 AT-capable
The ttyUSB0 is detected as QCDM capable by ModemManager. I think
it's only used for debugging with ModemManager --debug for sending
custom AT commands though. ModemManager already can manage data
connection using the USB QMI ports that are already handled by the
qmi_wwan.c driver.
To enable the MUX or NMEA ports, it seems that something needs to be
done additionally to enable them, maybe via the DIAG or TCMD port.
It might be just a NVRAM setting somewhere, but I have no idea what
NVRAM settings may need changing for that.
The TCMD port seems to be a Motorola custom protocol for testing
the modem and to configure it's NVRAM and seems to work just fine
based on a quick test with a minimal tcmdrw tool I wrote.
The voice modem AT-capable port seems to provide only partial
support, and no PM support compared to the TS 27.010 based UART
wired directly to the modem.
The UARTs added with this change are the same product IDs as the
Motorola Mapphone Android Linux kernel mdm6600_id_table. I don't
have any mdm9600 based devices, so I have only tested these on
mdm6600 based droid 4.
Then for the class 0x0a (CDC Data) mode, the Motorola Mapphone Android
Linux kernel driver moto_flashqsc.c just seems to change the
port->bulk_out_size to 8K from the default. And is only used for
flashing the modem firmware it seems.
I've verified that flashing the modem with signed firmware works just
fine with the option driver after manually toggling the GPIO pins, so
I've added droid 4 modem flashing mode to the option driver. I've not
added the other devices listed in moto_flashqsc.c in case they really
need different port->bulk_out_size. Those can be added as they get
tested to work for flashing the modem.
After this patch the output of /sys/kernel/debug/usb/devices has

I -thought- I had fixed this entirely, but it looks like that I didn't
test this thoroughly enough as we apparently still make one big mistake
with nv50_msto_atomic_check() - we don't handle the following scenario:
* CRTC #1 has n VCPI allocated to it, is attached to connector DP-4
which is attached to encoder #1. enabled=y active=n
* CRTC #1 is changed from DP-4 to DP-5, causing:
* DP-4 crtc=#1→NULL (VCPI n→0)
* DP-5 crtc=NULL→#1
* CRTC #1 steals encoder #1 back from DP-4 and gives it to DP-5
* CRTC #1 maintains the same mode as before, just with a different
connector
* mode_changed=n connectors_changed=y
(we _SHOULD_ do VCPI 0→n here, but don't)
Once the above scenario is repeated once, we'll attempt freeing VCPI
from the connector that we didn't allocate due to the connectors
changing, but the mode staying the same. Sigh.
Since nv50_msto_atomic_check() has broken a few times now, let's rethink
things a bit to be more careful: limit both VCPI/PBN allocations to
mode_changed || connectors_changed, since neither VCPI or PBN should
ever need to change outside of routing and mode changes.

* Fix accidental reversal of clock and bpp arguments in

Pull rdma fixes from Doug Ledford:
"Fairly small pull request for -rc3. I'm out of town the rest of this
week, so I made sure to clean out as much as possible from patchworks
in enough time for 0-day to chew through it (Yay! for 0-day being back
online! :-)). Jason might send through any emergency stuff that could
pop up, otherwise I'm back next week.
The only real thing of note is the siw ABI change. Since we just
merged siw *this* release, there are no prior kernel releases to
maintain kernel ABI with. I told Bernard that if there is anything
else about the siw ABI he thinks he might want to change before it
goes set in stone, he should get it in ASAP. The siw module was around
for several years outside the kernel tree, and it had to be revamped
considerably for inclusion upstream, so we are making no attempts to
be backward compatible with the out of tree version. Once 5.3 is
actually released, we will have our baseline ABI to maintain.
Summary:
- Fix a memory registration release flow issue that was causing a
WARN_ON (mlx5)
- If the counters for a port aren't allocated, then we can't do
operations on the non-existent counters (core)
- Check the right variable for error code result (mlx5)
- Fix a use after free issue (mlx5)
- Fix an off by one memory leak (siw)
- Actually return an error code on error (core)
- Allow siw to be built on 32bit arches (siw, ABI change, but OK
since siw was just merged this merge window and there is no prior
released kernel to maintain compatibility with and we also updated
the rdma-core user space package to match)"
