[PATCH 1/3] drm/amdgpu: Stop returning EINVAL during profile switch

[Russell, Kent]

Don't return an error after switching to the CUSTOM profile,
if there aren't any CUSTOM values passed in. The CUSTOM profile
is already applied, so if no other arguments are passed, just
return instead of throwing -EINVAL when successful
