Message-Id: <1340978140-11572-2-git-send-email-broonie@opensource.wolfsonmicro.com> Date: Fri, 29 Jun 2012 14:55:40 +0100 From: Mark Brown <broonie@...nsource.wolfsonmicro.com> To: Samuel Ortiz <sameo@...ux.intel.com> Cc: linux-kernel@...r.kernel.org, patches@...nsource.wolfsonmicro.com, Mark Brown <broonie@...nsource.wolfsonmicro.com> Subject: [PATCH 2/2] mfd: wm8994: Also restore GPIO IRQ masks after reset This ensures that if we are using a GPIO as a wake source it continues to function while we're suspended.
