Deren Wu a99d21cefd mmc: vub300: fix invalid response handling ... We may get an empty response with zero length at the beginning of the driver start and get following UBSAN error. Since there is no content(SDRT_NONE) for the response, just return and skip the response handling to avoid this problem.
