[PATCH 16/25] drm/amd/display: Remove i2caux folder

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

 



From: David Francis <David.Francis@xxxxxxx>

[Why]
It is huge, unmaintainable, needlessly layered, and obsolete

[How]
Remove it.  All of it.  Also remove the i2caux struct in
dc_context and the code that created and destructed it
