From fe75fe0e041bd5badc6a0be0c3918590198df2a0 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Fri, 30 Dec 2011 23:38:03 +0800 Subject: [PATCH] ASoC: Fix return value of wm8962_gpio_direction_out() We can't just pass back the return value of snd_soc_update_bits() as it will be 1 if a bit changed rather than zero.
