Looks good to me.

mode->name is a character array in a structure, checking it's
address is pointless and causes a warning with some compilers:

drivers/gpu/drm/drm_connector.c:144:15: error: address of array 'mode->name' will always evaluate to 'true'
      [-Werror,-Wpointer-bool-conversion]
                      mode->name ? mode->name : "",
                      ~~~~~~^~~~ ~
include/drm/drm_print.h:366:29: note: expanded from macro 'DRM_DEBUG_KMS'
        drm_dbg(DRM_UT_KMS, fmt, ##__VA_ARGS__)
                                   ^~~~~~~~~~~

Remove the check here.
