[alsa-devel] [PATCH] ASoC: Fix build failure in soc-core.c
by Jarkko Nikula 01 Dec '10

01 Dec '10

Commit 2eea392 "ASoC: Add support for optional auxiliary dailess codecs" causes a build failure in soc-core.c: soc_probe_aux_dev since code tries to access non-existing struct snd_soc_dapm_context and struct snd_soc_card members. Root cause for this was a double accident. Author sent the RFC patch from top of another patch set and the RFC got committed. Fix the build failure by removing the code line that depends on that another patch set.

[alsa-devel] [PATCH] ASoC: WM8731: Fix incorrect mask for bypass path disable
by Dimitris Papastamos 01 Dec '10

According to the datasheet the bypass path enable/disable is bit 3 therefore we need 0x8 and not 0x4.
