If Calling hibmc_mm_init() failed in hibmc_load(), the hibmc_unload()
will access a NULL pointer, as it don't call ww_mutex_init() to
initialize mode_config.connection_mutex but try to lock it when
calling drm_atomic_helper_shutdown().

In some causes, HPD signals will jitter when plugging in
or unplugging HDMI.
Rescheduling the hotplug work for a second when EDID may still be
readable but HDP is disconnected, and fixes this issue.

Hi,
I think it will cause memory leaks if too many nonblock commit works return
-EBUSY.
You can try to send large number of nonblock commits by
drmModeAtomicCommit().

It is wrong to call stall_checks() after allocating memory
for struct drm_crtc_commit as it will cause memory leaks if
too many nonblock commit works return -EBUSY.
So it needs to call stall_checks() before allocate drm_crtc_commit.
