[PATCH drm-misc-next 0/3] Fixes for vc4 hotplug rework

[Danilo Krummrich]

Hi,

I've found a few potential issues left after the hotplug rework.

In vc4_hdmi.c we're missing two mutex_unlock() calls when the device is
unplugged.

vc4_crtc and vc4_plane seem to miss some drm_dev_enter()/drm_dev_exit() calls
to protect against resource access after the device/driver is unbound, but the
DRM potentially isn't freed yet and userspace can still call into the driver.

Danilo Krummrich (3):
  drm/vc4: hdmi: unlock mutex when device is unplugged
  drm/vc4: plane: protect device resources after removal
  drm/vc4: crtc: protect device resources after removal
