From 64964e82644e9f809dc83019186c21ed5b70aa56 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 31 Oct 2011 19:02:13 +0000 Subject: [PATCH] ASoC: Fix return value of wm5100_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.
