[PATCH 03/20] drm/kms-helpers: Extract drm_modeset_helper.[hc]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



While reviewing docs I spotted that we have a few functions that
really just don't fit into their containing helper library section.
Extract them and shovel them all into a new library for random one-off
aux stuff.
