Subject: [PATCH 0/3] drm/vc4: hdmi: Interrupt fixes

Hi,

Those are three fixes for race conditions we currently have in the vc4 HDMI
driver with regard to the interrupts handling.

The first two are fixing an issue where the handler will be removed by devm
after the resources it uses have been free'd already.

The last one is there to deal with an interrupt coming in the window between
the end of the driver's bind and the  DRM device registration.

Let me know what you think,
Maxime

Maxime Ripard (3):
  drm/vc4: hdmi: Drop devm interrupt handler for CEC interrupts
  drm/vc4: hdmi: Drop devm interrupt handler for hotplug interrupts
  drm/vc4: hdmi: Only call into DRM framework if registered
