Merge v6.2-rc6 into drm-next
Due to holidays we started -next with more -fixes in-flight than
usual, and people have been asking where they are. Backmerge to get
things better in sync.
Conflicts:
- Tiny conflict in drm_fbdev_generic.c between variable rename and
missing error handling that got added.
- Conflict in drm_fb_helper.c between the added call to vgaswitcheroo
in drm_fb_helper_single_fb_probe and a refactor patch that extracted
lots of helpers and incidentally removed the dev local variable.
Readd it to make things compile.
