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

Every user of this function either uses component_compare_of or
something equivalent. Most of them immediately put the device node as
well. Convert these users to component_match_add_of and remove
drm_of_component_match_add.
