1a701ea924 drm/amdgpu: prevent memory leaks in AMDGPU_CS ioctl
Error out if the AMDGPU_CS ioctl is called with multiple SYNCOBJ_OUT and/or
TIMELINE_SIGNAL chunks, since otherwise the last chunk wins while the
allocated array as well as the reference counts of sync objects are leaked.

We need to set certain power gating flags after we determine
if the firmware version is sufficient to support gfxoff.
Previously we set the pg flags in early init, but we later
we might have disabled gfxoff if the firmware versions didn't

2d683eaaee net: cpsw: fix NULL pointer exception in the probe error path
In certain cases when the probe function fails the error path calls
cpsw_remove_dt() before calling platform_set_drvdata(). This is an
issue as cpsw_remove_dt() uses platform_get_drvdata() to retrieve the
cpsw_common data and leds to a NULL pointer exception. This patches
fixes it by calling platform_set_drvdata() earlier in the probe.

3b5be16c7e modules: page-align module section allocations only for arches supporting strict module rwx
We should keep the case of "#define debug_align(X) (X)" for all arches
without CONFIG_HAS_STRICT_MODULE_RWX ability, which would save people, who
are sensitive to system size, a lot of memory when using modules,
especially for embedded systems. This is also the intention of the
original #ifdef... statement and still valid for now.

Note that this still keeps the effect of the fix of the following commit,
38f054d549 ("modules: always page-align module section allocations"),
since when CONFIG_ARCH_HAS_STRICT_MODULE_RWX is enabled, module pages are
aligned.

Re-triggering a reg_process_hint with the last request on all events,
can make the regulatory domain fail in case of multiple WiFi modules. On
slower boards (espacially with mdev), enumeration of the WiFi modules
can end up in an intersected regulatory domain, and user cannot set it
with 'iw reg set' anymore.

This is happening, because:
- 1st module enumerates, queues up a regulatory request
- request gets processed by __reg_process_hint_driver():
  - checks if previous was set by CORE -> yes
    - checks if regulator domain changed -> yes, from '00' to e.g. 'US'
      -> sends request to the 'crda'
- 2nd module enumerates, queues up a regulator request (which triggers
  the reg_todo() work)
- reg_todo() -> reg_process_pending_hints() sees, that the last request
  is not processed yet, so it tries to process it again.
  __reg_process_hint driver() will run again, and:
  - checks if the last request's initiator was the core -> no, it was
    the driver (1st WiFi module)
  - checks, if the previous initiator was the driver -> yes
    - checks if the regulator domain changed -> yes, it was '00' (set by
      core, and crda call did not return yet), and should be changed to 'US'

------> __reg_process_hint_driver calls an intersect

Besides, the reg_process_hint call with the last request is meaningless
since the crda call has a timeout work. If that timeout expires, the
first module's request will lost.

b67fd72e84 cfg80211: Fix Extended Key ID key install checks
Fix two shortcomings in the Extended Key ID API:

 1) Allow the userspace to install pairwise keys using keyid 1 without
    NL80211_KEY_NO_TX set. This allows the userspace to install and
    activate pairwise keys with keyid 1 in the same way as for keyid 0,
    simplifying the API usage for e.g. FILS and FT key installs.

 2) IEEE 802.11 - 2016 restricts Extended Key ID usage to CCMP/GCMP
    ciphers in IEEE 802.11 - 2016 "9.4.2.25.4 RSN capabilities".
    Enforce that when installing a key.

6de3c9e3f6 ALSA: usb-audio: Fix invalid NULL check in snd_emuusb_set_samplerate()
The quirk function snd_emuusb_set_samplerate() has a NULL check for
the mixer element, but this is useless in the current code.  It used
to be a check against mixer->id_elems[unitid] but it was changed later
to the value after mixer_eleme_list_to_info() which is always non-NULL
due to the container_of() usage.

This patch fixes the check before the conversion.

While we're at it, correct a typo in the comment in the function,
too.

4651d1802f net/smc: make sure EPOLLOUT is raised
Currently, we are only explicitly setting SOCK_NOSPACE on a write timeout
for non-blocking sockets. Epoll() edge-trigger mode relies on SOCK_NOSPACE
being set when -EAGAIN is returned to ensure that EPOLLOUT is raised.
Expand the setting of SOCK_NOSPACE to non-blocking sockets as well that can
use SO_SNDTIMEO to adjust their write timeout. This mirrors the behavior
that Eric Dumazet introduced for tcp sockets.
