[PATCH 1/2] drm/crtc_helper/set_config: Remove redundant handling when set->fb is NULL

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

 



We've done sanity NULL pointer check on set->fb at the beginning of
drm_crtc_helper_set_config() and bailed out if necessary, thus any later on
check or case handling is redundant.
