From 11e16eb365f4f6979cfcb2a2d379338b383590d9 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 3 Nov 2010 14:45:07 -0400 Subject: [PATCH] ASoC: Use pm_wakeup_event() in WM8962 jack detection Ensure that the system does not suspend while we process a WM8962 jack event by using pm_wakeup_event() to block the suspend while we're waiting for the jack to settle. Use a slightly longer timeout than the jack waits to allow for other stuff to take over and delays in scheduling.
