    mmc,sdio: helper function for transfer padding · ad3868b2
    Pierre Ossman 提交于
    There are a lot of crappy controllers out there that cannot handle
    all the request sizes that the MMC/SD/SDIO specifications require.
    In case the card driver can pad the data to overcome the problems,
    this commit adds a helper that calculates how much that padding
    should be.
    
    A corresponding helper is also added for SDIO, but it can also deal
    with all the complexities of splitting up a large transfer efficiently.
