[PATCH v3 0/3] drm: Add component_match_add_of and convert users of drm_of_component_match_add

[Sean Anderson]

This series adds a new function component_match_add_of to simplify the
common case of calling component_match_add_release with
component_release_of and component_compare_of. There is already
drm_of_component_match_add, which allows for a custom compare function.
However, all existing users just use component_compare_of (or an
equivalent).

Changes in v3:
- Rebase onto drm/drm-next

Changes in v2:
- Split off conversion from helper addition
- Rebase onto drm/drm-next

Sean Anderson (3):
  component: Add helper for device nodes
  iommu/sound: Use component_match_add_of helper
  drm: Convert users of drm_of_component_match_add to
    component_match_add_of
