From: Kuninori Morimoto Date: Mon, 3 Mar 2014 07:42:55 +0000 (-0800) Subject: ASoC: rsnd: use mod array instead of list on rdai X-Git-Tag: v3.14.28+ltsi~949 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2ba4a040ae303bc06bc4127da14e049f9924628;p=platform%2Fkernel%2Flinux-stable.git ASoC: rsnd: use mod array instead of list on rdai struct rsnd_dai_stream used list for mod list. It added only odd flexibility to current driver, and it is a factor which makes extendibility difficult. rsnd use mod array instead of list from now.
