Subject: mmc: omap_hsmmc: fix cmd23 multiblock read/write
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=2177fa9482a92c25c36eb506d38a2c1944b60adc;p=deliverable%2Flinux.git

mmc: omap_hsmmc: fix cmd23 multiblock read/write

Check for set block count command fails always since host->cmd is set
to NULL in the same function incorrectly. Correct host->cmd usage properly.
