I tested this patch with a SD tester (SGDK320). As the commit log, this patch could pass the R1 response. So, Tested-by: Yoshihiro Shimoda <yoshihiro.shimoda...@renesas.com> However, I think the MMC block layer should check the brq->stop.resp[0] because brq->stop.error should be zero in this case and mmc_blk_cmd_recovery() is not called in mmc_blk_err_check().
