Subject: [PATCH] spl: mmc: Fix compiler warning with CONFIG_DM_MMC
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit
Since commit 4188ba3 we get the following warning on rockchip boards:
common/spl/spl_mmc.c:31:24: warning: âmmcâ may be used uninitialized in this function [-Wmaybe-uninitialized]
count = mmc->block_dev.block_read(0, sector, 1, header);
^
common/spl/spl_mmc.c:251:14: note: âmmcâ was declared here
struct mmc *mmc;
Correct this by move the variable init earlier.
