The only exceptio is the opregion stuff where we may (in theory at least) get a request from the BIOS already during driver init as soon as the backlight setup has been done. In which case we can still get the INVALID_PIPE from intel_get_pipe_from_connector(). So leave that check in place, and add a comment explaining why. For the rest, if we still manage to get here with INVALID_PIPE on VLV/CHV we will now get a WARN from the lower level functions and can then actually investigate further. v2: Leave the check in the BIOS related code (Jani) Cc: Jani Nikula Signed-off-by: Ville Syrjälä Reviewed-by: Jani Nikula Signed-off-by: Daniel Vetter --- Reading git-diff-tree failed
