Subject: mx51evk: Fix error handling in board_mmc_init()
X-Git-Tag: v2015.01-rc2~3^2~13
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=d6af507d5a568289a90984541e1b5971ede5cc9c;p=oweals%2Fu-boot.git

mx51evk: Fix error handling in board_mmc_init()

When an invalid USDHC port is passed we should return -EINVAL instead of 0.

Also, return the error immediately on fsl_esdhc_initialize() failure.
