Subject: ASoC: soc-core: Generalize snd_soc_prefix_map and rename to snd_soc_codec_conf
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=ff819b8357df0ca9903ff7c9ad518b949c410123;p=deliverable%2Flinux.git

ASoC: soc-core: Generalize snd_soc_prefix_map and rename to snd_soc_codec_conf

The snd_soc_codec_conf struct now holds codec specific configuration
information.

A new configuration option has been added to allow machine drivers to
override the compression type set by the codec driver.

In the absence of providing an snd_soc_codec_conf struct or when providing
one but not setting the compress_type member to anything, the one supplied
by the codec driver will be used instead.  In all other cases the one
set in the snd_soc_codec_conf struct takes effect.
