From 43fc6bce37ff39ab5010afadf1ea86e7cc9c2b37 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Sat, 9 Jun 2012 11:07:56 +0800 Subject: gpiolib: wm8994: Pay attention to the value set when enabling as output commit 8cd578b6e28693f357867a77598a88ef3deb6b39 upstream. Not paying attention to the value being set is a bad thing because it means that we'll not set the hardware up to reflect what was requested. Not setting the hardware up to reflect what was requested means that the caller won't get the results they wanted.
