Subject: ASoC: Constify struct snd_soc_codec_driver
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=001ae4c0350a35e8358514326e5c3d165357979a;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ASoC: Constify struct snd_soc_codec_driver

Allow the CODEC driver structure to be marked const by making all
the APIs that use it do so.
