1eda919126 nl80211: reset regdom when reloading regdb
Reload the regdom when the regulatory db is reloaded.
Otherwise, the user had to change the regulatoy domain
to a different one and then reset it to the correct
one to have a new regulatory db take effect after a
reload.

65cc4ad62a ALSA: hda/cs8409: Set PMSG_ON earlier inside cs8409 driver
For cs8409, it is required to run Jack Detect on resume.
Jack Detect on cs8409+cs42l42 requires an interrupt from
cs42l42 to be sent to cs8409 which is propogated to the driver
via an unsolicited event.
However, the hda_codec drops unsolicited events if the power_state
is not set to PMSG_ON. Which is set at the end of the resume call.
This means there is a race condition between setting power_state
to PMSG_ON and receiving the interrupt.
To solve this, we can add an API to set the power_state earlier
and call that before we start Jack Detect.
This does not cause issues, since we know inside our driver that
we are already initialized, and ready to handle the unsolicited
events.

1d72d9f960 Input: elantech - fix stack out of bound access in elantech_change_report_id()
The array param[] in elantech_change_report_id() must be at least 3
bytes, because elantech_read_reg_params() is calling ps2_command() with
PSMOUSE_CMD_GETINFO, that is going to access 3 bytes from param[], but
it's defined in the stack as an array of 2 bytes, therefore we have a
potential stack out-of-bounds access here, also confirmed by KASAN:

e1f5e84820 Input: iqs626a - prohibit inlining of channel parsing functions
Some automated builds report a stack frame size in excess of 2 kB for
iqs626_probe(); the culprit appears to be the call to iqs626_parse_prop().

To solve this problem, specify noinline_for_stack for all of the
iqs626_parse_*() helper functions which are called inside a for loop
within iqs626_parse_prop().

As a result, a build with '-Wframe-larger-than' as low as 512 is free of
any such warnings.

9222ba68c3 Input: i8042 - add deferred probe support
We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA.  It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready.  Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module.  However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.

This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above.  When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.

The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry.  As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.

The deferred probe part is based on Fabio's initial work.

8886a57974 fpga: region: Use standard dev_release for class driver
The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.

The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.

7c0ffcd40b drm/msm/gpu: Respect PM QoS constraints
Re-work the boost and idle clamping to use PM QoS requests instead, so
they get aggreggated with other requests (such as cooling device).

This does have the minor side-effect that devfreq sysfs min_freq/
max_freq files now reflect the boost and idle clamping, as they show
(despite what they are documented to show) the aggregated min/max freq.
Fixing that in devfreq does not look straightforward after considering
that OPPs can be dynamically added/removed.  However writes to the
sysfs files still behave as expected.

Lets increase this inactivity threshold to 50ms (same as the current
