Subject: mmc: sdhci: don't clobber adjacent registers
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e113fe3c06e34c9d29bd8952955558d585e4f80c;p=u-boot.git

mmc: sdhci: don't clobber adjacent registers

SDHCI_HOST_CONTROL is a byte-sized register, so don't write to it
as if it were a long, as that would result in clobbering the three
registers following.
