[PATCH] OMAP: hsmmc: Fix mux for non-OMAP pins

From: Thomas Weber
Date: Tue Sep 06 2011 - 04:08:44 EST


The Devkit8000 uses a TWL4030 pin for card detection.
Thats why the error:
_omap_mux_init_gpio: Could not set gpio192
occurs.

This patch checks that the pin is on OMAP before
calling omap_mux_init_gpio.
