The following commit has been merged in the linux branch: commit a90c31a3b70bcef915ffddacb8cbb4e63de33415 Author: Sascha Hauer s.hauer@pengutronix.de Date: Tue Oct 6 09:18:17 2009 +0200
pcm970 mmc: Fix ro switch
We have to use mxc_gpio_mode() for the card detection pin instead of mxc_gpio_setup_multiple_pins() because the latter does a gpio_request() and thus a later gpio_request() fails.
