drm/imagination: Drain interrupts before suspending the GPU

[PATCH 0/2] drm/imagination: Drain interrupts before suspending the GPU

Posted by Alessio Belle 4 weeks, 1 day ago

The first commit is the actual fix and will need backporting to stable
branches, though some of the code being removed didn't exist prior to
6.16 so the patch will need adaptations.

The second commit tries to prevent similar issues and doesn't need
backporting.
