Commit Message

Geert Uytterhoeven Aug. 16, 2023, 9:50 a.m. UTC 
Now that drm_device is embedded in shmob_drm_device, we can use
a container_of()-based helper to get the shmob_drm_device pointer from
the drm_device, instead of using the deprecated drm_device.dev_private
field.

While at it, restore reverse Xmas tree ordering of local variable
declarations.
