From 219b93f5252086c8c8d647c77fc9e1377aab0c8d Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 28 Oct 2008 13:02:31 +0000 Subject: [PATCH] ASoC: Remove DAPM restriction on mixer control name lengths As well as ensuring that UI-relevant parts of control names don't get truncated in the DAPM code this avoids conflicts in long control names that differ only at the end of a long string.
