[PATCH 00/25] Amdgpu plugin cleanups and fixes

This series is a subset of previously posted:
https://lore.kernel.org/criu/CAEWA0a4ghpPeQjg1ETiQysGj5agfWwJRvMbWzhrYL5r8WZ5H7Q@mail.gmail.com/T/#mfb4ab4866a0cb440961be7170d0e107fab7eedf2

It only contains the fixes and cleanups with the render node hacks removed.

Most of the patches have already been reviewed, with just five new ones, since I
did find some more problems, mostly around incorrect usage of pr_perror and some
helpers not using the errno correctly. One of the patches reduces the amount of
pr_debug in normal operation as agreed during the review of the above linked
series.

The new patches are these:
  plugins/amdgpu: Reduce amount of debug logging a little bit
  plugins/amdgpu: Do not eat the errno in kmtIoctl
  plugins/amdgpu: Fix open_drm_render_device()
  plugins/amdgpu: Check sdma operation type early and once
  plugins/amdgpu: Fix remaining wrong usages of pr_perror

Intent is to hopefully get those remaining ones reviewed, merge the series, and
then proceed with the more complicated design work for properly supporting pure
render node applications.

Regards,

Tvrtko
