ARM: imx: refactor mxc_iomux_mode()
Refactor mxc_iomux_mode(): - since it always returns 0 make it to return void - remove unnecessary ret variable - declare variables according to the kernel coding style Signed-off-by: Dmitry Voytik <voytikd@gmail.com> Signed-off-by: Shawn Guo <shawn.guo@linaro.org>
