As we are not using the sysfs infrastructure anymore, link to it is
removed. And global srm data and mutex to protect it are removed,
with required handling at revocation check function.
Yet to test hence RFC tag is added.

Remove drm_connector_unregister() since it should be
used only by drivers that call drm_dev_register
explicitly.
Also, call the DRM cleanups directly, instead of
(ab)using the destroy hooks, for readability reasons.

The ast driver inherits from DRM's CRTC state, but still uses the atomic
helper for struct drm_crtc_funcs.reset, drm_atomic_helper_crtc_reset().
The helper only allocates enough memory for the core CRTC state. That
results in an out-ouf-bounds access when duplicating the initial CRTC
state. Simpli

1db8c142b6c5 (drm/scheduler: Add drm_sched_suspend/resume_timeout()) made
the job_list_lock IRQ safe in as the suspend/resume calls were expected to
be called from IRQ context. This usage never materialized in upstream.
Instead amdgpu started locking the job_list_lock in an IRQ unsafe way in
amdgpu

Problem: do_unregister_framebuffer() might return before the device is
fully cleaned up, due to userspace having a file handle for /dev/fb0
open. Which can result in drm driver not being able to grab resources
(and fail initialization) because the firmware framebuffer still holds
them. Reportedly

This adds support for the iTE IT6505.
This device can convert DPI signal to DP output.

Hello,
syzbot found the following crash on:
HEAD commit:def9d278 Linux 5.5-rc7
git tree: upstream
console output: https://syzkaller.appspot.com/x/log.txt?x=13000685e0
kernel config: https://syzkaller.appspot.com/x/.config?x=83c00afca9cf5153
dashboard link: https://syzkaller.appspot
I have recently (since the New Year) been experiencing regular GPU hangs
which typically render the system unusable.
During the hangs the kernel buffer is filled with messages of the form

Sorry, just noticed that this has not gone through yet.

Add rate limiting of the 'pp done time out' warnings since these
warnings can quickly fill the dmesg buffer.
