    mmc: card: fixing an false identification of SANITIZE command · a82e484e
    Yaniv Gardi 提交于
    Inside the routine mmc_blk_ioctl_cmd() the sanitize command is
    identified according to the value of bits 16-23 of the argument.
    
    but what happens if a different command is sent, and only by
    chance, bits 16-23 contain the value of SANITIZE command ?
    In that case a SANITIZE command will be falsely identified.
    In order to prevent such a case, the condition is expanded and
    now it also checks the opcode itself, and verifies that it is an
    MMC_SWITCH opcode.
