From 2927d6eeca0a5004d81fa5bedbdf3f2b1b842903 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Thu, 17 Jul 2008 15:06:50 +0100 Subject: ALSA: ASoC: Refactor DAPM event handler The DAPM event callback code has many layers of indentation, taking it over 80 columns. Refactor the code to give less indentation in order to avoid checkpatch issues on further changes and exploding indentation.
