Subject: drm/komeda: plane: switch to plane reset helper
Git-commit: 8a0982b60f5a4a66c8a28eed37769021c20d8c50
Patch-mainline: v5.19-rc1

komeda_plane_reset() does the state initialisation by copying a lot of
the code found in the __drm_atomic_helper_plane_reset(). Let's switch to
that helper and reduce the boilerplate.
