Subject: mmc: block: rename data to blkdata
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=7db3028e00f0d19d4ab10d3d5f38afb1d7814861;p=openwrt%2Fstaging%2Fblogic.git

mmc: block: rename data to blkdata

The struct mmc_blk_request contains an opaque void *data that
is actually only used to store a pointer to a per-request
struct mmc_blk_data. This is confusing, so rename the member
to blkdata and forward-declare the block.c local struct.
