[PATCH v4 0/7] Cleanup and fixes in drmm_add_action_or_reset usage

[Himal Prasad Ghimiray]

drmm_add_action_or_reset automatically triggers the corresponding action
if there's a failure. However, certain functions were previously relying
on return codes to trigger cleanup, leading to redundant calls. Removed
these functions to prevent multiple invocations.

In case of a failure, drmm_add_action_or_reset automatically triggers a
warning message, such as 'failed to add action "action_name" for
"drm_device".' Despite this, the driver was redundantly issuing similar
warning messages upon failure, offering no additional value. Remove these 
redundant warnings calls.

When encountering failures in sysfs creations or
drmm_add_action_or_reset, errors were previously suppressed. Now,
escalate these errors up the call chain, ensuring they are appropriately
handled in the caller.

Himal Prasad Ghimiray (7):
  drm/xe: Simplify function return using drmm_add_action_or_reset()
  drm/xe: Remove sysfs only once on action add failure
  drm/xe: call free_gsc_pkt only once on action add failure
  drm/xe: Return NULL in case of drmm_add_action_or_reset failure
  drm/xe/gt: Abort driver load for sysfs creation failure
  drm/xe/tile: Abort driver load for sysfs creation failure
  drm/xe/pm: Capture errors and handle them
