Subject: [MMC] PXA and i.MX: don't avoid sending stop command on error
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58741e8b3603e56c3699550e8bc89cb136329343;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[MMC] PXA and i.MX: don't avoid sending stop command on error

Always send a stop command at the end of a data transfer.  If we avoid
sending the stop command, some cards remain in data transfer mode, and
refuse to accept further read/write commands.
