Commit Message

Adrián Larumbe Nov. 28, 2024, 9:06 p.m. UTC
Drop the deprecated DRM driver allocation method in favour of
devm_drm_dev_alloc(). Overall just make it the same as in Panthor.
Also discard now superfluous generic and platform device pointers inside
the main panfrost device structure.

Some ancient checkpatch issues unearthed as a result of these changes
were also fixed, like lines too long or double assignment in one line.
