From d019403a777e9978767d0551fa55f624baf7df09 Mon Sep 17 00:00:00 2001 From: Tzung-Bi Shih Date: Mon, 23 Aug 2021 23:33:23 +0800 Subject: [PATCH] ASoC: rt1015: remove possible unused variable `bclk_ms' bclk_ms is possible unused by using the given config (see [1]). sound/soc/codecs/rt1015.c:724:2: warning: Value stored to 'bclk_ms' is never read [clang-analyzer-deadcode.DeadStores] bclk_ms = frame_size > 32; ^ ~~~~~~~~~~~~~~~ In addition, bclk_ms is meaningless and confusing after applying commit a5db2ca51367 ("ASoC: rt1015: remove unneeded variables in rt1015_priv"). The "> 32" in the expression looks like a typo but it was not. Let's remove the confusing variable bclk_ms.
