When an Advanced RPMB command\nreturns an EHS, ufshcd_advanced_rpmb_req_handler() copies it right after\nthe 40-byte header and writes 8 bytes past the end of the buffer.\n\nLet each BSG transport pass its reply buffer size to bsg_setup_queue()\nand have ufs_bsg request sizeof(struct ufs_rpmb_reply), so the full\nreply reaches user space. Other transports keep SCSI_SENSE_BUFFERSIZE."
