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).
I can split the second commit up if that is easier to review.
Sean Anderson (2):
component: Add helper for device nodes
drm: Convert users of drm_of_component_match_add to
component_match_add_of

FWIW you'll need to rebase the IOMMU changes on 6.2-rc1 anyway - mtk_iommu stops using component_match_add_release() at all. Thanks, Robin.

I am preparing v2 of this series, but I don't see these changes on drm-next, which seems to have been updated to at least 6.2-rc1. I tried searching for these changes on lore [1], but I don't see them there either. Do you have a commit hash/lore link for these changes? --Sean [1] https://lore.kernel.org/all/?q=dfn%3Adrivers%2Fiommu%2Fmtk_iommu.c+b%3Acomponent
