Pull drm fixes from Dave Airlie:
 "Bit of an uptick in patch count this week, though it's all relatively
  small overall.

  I suspect msm has been queuing up a few fixes to skew it here.
  Otherwise amdgpu has a scattered bunch of small fixes, and then some
  vc4, i915.

  virtio-gpu changes an rc1 introduced uAPI mistake, and makes it
  operate more like other drivers. This should be fine as no userspace
  relies on the behaviour yet.

  Summary:

  dma-buf:
   - memory leak fix

  msm:
   - kasan found memory overwrite
   - mmap flags
   - fencing error bug
   - ioctl NULL ptr
   - uninit var
   - devfreqless devices fix
   - dsi lanes fix
   - dp: avoid unpowered aux xfers

  amdgpu:
   - IP discovery based enumeration fixes
   - vkms fixes
   - DSC fixes for DP MST
   - Audio fix for hotplug with tiled displays
   - Misc display fixes
   - DP tunneling fix
   - DP fix
   - Aldebaran fix

  amdkfd:
   - Locking fix
   - Static checker fix
   - Fix double free

  i915:
   - backlight regression
   - Intel HDR backlight detection fix
   - revert TGL workaround that caused hangs

  virtio-gpu:
   - switch back to drm_poll

  vc4:
   - memory leak
   - error check fix
   - HVS modesetting fixes"

 "Including fixes from wireless, and wireguard.

  Mostly scattered driver changes this week, with one big clump in

  Current release - regressions:

   - smc: keep smc_close_final()'s error code during active close

  Current release - new code bugs:

   - iwlwifi: various static checker fixes (int overflow, leaks, missing
     error codes)

   - rtw89: fix size of firmware header before transfer, avoid crash

   - mt76: fix timestamp check in tx_status; fix pktid leak;

   - mscc: ocelot: fix missing unlock on error in ocelot_hwstamp_set()

  Previous releases - regressions:

   - smc: fix list corruption in smc_lgr_cleanup_early

   - ipv4: convert fib_num_tclassid_users to atomic_t

  Previous releases - always broken:

   - tls: fix authentication failure in CCM mode

   - vrf: reset IPCB/IP6CB when processing outbound pkts, prevent

getrusage(RUSAGE_THREAD) with nohz_full may return shorter utime/stime
than the actual time.

task_cputime_adjusted() snapshots utime and stime and then adjust their
sum to match the scheduler maintained cputime.sum_exec_runtime.
Unfortunately in nohz_full, sum_exec_runtime is only updated once per
second in the worst case, causing a discrepancy against utime and stime
that can be updated anytime by the reader using vtime.

To fix this situation, perform an update of cputime.sum_exec_runtime
when the cputime snapshot reports the task as actually running while
the tick is disabled. The related overhead is then contained within the
relevant situations.

Before commit faa041a40b9f ("ipv4: Create cleanup helper for fib_nh")
changes to net->ipv4.fib_num_tclassid_users were protected by RTNL.

After the change, this is no longer the case, as free_fib_info_rcu()
runs after rcu grace period, without rtnl being held.
