[PATCH 11/11] drm/amd/display: Drop CONFIG_DRM_AMD_DC_DMUB guards

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

 



[Why]
Support for DMUB only depends on support for DC. It doesn't use floating
point so we don't need to guard it by any specific DCN revision.

[How]
Drop the guards and cleanup the newlines around each one.
