From 3e02d41417c3f2e569e80ce10f613e9ac2f2321d Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Fri, 7 Mar 2014 16:34:23 +0000 Subject: [PATCH] ASoC: arizona: Calculate FLL gain last No part of the FLL calculation depends on the value determined for the gain but the gain does depend on other values. In preparation for future updates this patch moves the gain to be the last thing calculated.
