Since we'll be allocating resources for kthread_create_worker() in the next commit (which could fail and require us to clean up the mess), let's simplify the cleanup process a bit by registering a drm_vblank_init_release() action for each drm_vblank_crtc so they're still cleaned up if we fail to initialize one of them.

Nvidia released some documentation on how CRC support works on their GPUs, hooray! So: this patch series implements said CRC support in nouveau, along with adding some special debugfs interfaces for some relevant igt-gpu-tools tests (already on the ML). First - we add some new functionality to kthread_work in the kernel, and then use this to add a new feature to DRM that Ville Syrj?l? came up
