[PATCH v5 03/22] drm/connector: Only register TV mode property if present

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

 



The drm_create_tv_properties() will create the TV mode property
unconditionally.

However, since we'll gradually phase it out, let's register it only if we
have a list passed as an argument. This will make the transition easier.
