Subject: mmc: remove confusing flag
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=be0192aae1aed3fbf172e3f9a22ec75392c1b175;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

mmc: remove confusing flag

The MMC_DATA_MULTI flag never had a proper definition of what it
means, so remove it and let the drivers check the block count in
the request.
