From fe2265e4833a3ebea426d748b5ecf8d3ff31edc8 Mon Sep 17 00:00:00 2001 From: Xiubo Li Date: Thu, 27 Feb 2014 17:49:52 +0800 Subject: [PATCH] ASoC: core: Set the default I/O up try regmap. For most CODEC drivers which the REGMAP is used, the soc_probe_codec() will do the stuff work of snd_soc_codec_set_cache_io(), which the CODEC drivers' ASoC probe will do too, and almost at the same time. This patch set the default I/O up try regmap, and then the CODEC drivers' stuff work of snd_soc_codec_set_cache_io() will be redundant, while if one CODEC driver needed to set it's own I/O, then it can rewrite the default ones. Then could we just discard the snd_soc_codec_set_cache_io() from the CODEC drivers' ASoC probe to simplify the code.
