From: Kuninori Morimoto Date: Thu, 15 Jun 2017 00:49:27 +0000 (+0000) Subject: ASoC: rsnd: rename "slots" related variable X-Git-Tag: v4.14-rc4~21^2~60^2~4^2~6 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1ff9593d2f27a48fbeeccd7fc253eed2a7102d16;p=platform%2Fkernel%2Flinux-rpi.git ASoC: rsnd: rename "slots" related variable Current Renesas sound driver has slots and slots_num in struct rsnd_dai, but these are very un-understandable naming (It had named from TDM slots). In this driver, the "slots" means total usable channels, and "stot_num" means SSI lane number if Multi SSI was used. To more understandable code, this patch renames "slots" to "max_channels", and "slots_num" to "ssi_lane", and replaces related functions name.
