[PATCH v3 22/41] drm: renesas: shmobile: Replace .dev_private with container_of()
From: Geert Uytterhoeven
Date: Wed Aug 16 2023 - 06:46:42 EST
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.
