    mmc: dw_mmc: Add RCRC handling · 26cc40d8
    Marek Vasut 提交于
    This patch adds check for command response CRC failure. The driver
    is currently ignoring CRC check failure on command resposes which
    have CRC atteched to it, which can be potentially dangerous. Even
    more grueling problem happens when the command response is followed
    by data transfer though, as in that case, the dwmci_data_transfer()
    function will spin until it reaches the 240s timeout.
