From 6fe17da00ba7046db2d3a952a930e127dcd7f06e Mon Sep 17 00:00:00 2001 From: Oder Chiou Date: Tue, 25 Nov 2014 09:51:41 +0800 Subject: [PATCH] ASoC: rt5677: Fix the issue that the regmap_range "rt5677_ranges" cannot be accessed After the patch "ASoC: rt5677: Use specific r/w function for DSP mode", the regmap_range "rt5677_ranges" was not registered in rt5677_regmap_physical, and it caused that the regmap_range "rt5677_ranges" cannot be accessed by the specific r/w function. The patch fixes this issue.
