Subject: [PATCH v2 0/8] Some Panfrost fixes and improvements

This is v2 of https://lore.kernel.org/dri-devel/20241014233758.994861-1-adrian.larumbe@collabora.com/

with while working on driver related stuff.

Changelog:

v2:

 - Added commit for removing unused Panfrost device structure member
 - Refactored how optional job interrupt reenabling during reset is handled
 - Make the way errors and successful return values are delivered from inside
  panfrost_mmu_as_get more according to standard.
 - Simplify unmapping of already mapped area when mapping the pages of a BO
 - Fixing management of runtime-PM reference counts when failing HW job submission.

Adrián Larumbe (8):
  drm/panfrost: Replace DRM driver allocation method with newer one
  drm/panfrost: Handle inexistent GPU during probe
  drm/panfrost: Handle job HW submit errors
  drm/panfrost: Handle error when allocating AS number
