[U-Boot] [PATCH 1/2] wandboard: Fix error handling in board_mmc_init()

[U-Boot] [PATCH 1/2] wandboard: Fix error handling in board_mmc_init()

[Fabio Estevam]

From: Fabio Estevam <fabio.estevam@freescale.com>

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

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