Subject: [PATCH v3 09/13] ASoC: ti: omap-mcbsp-st: Remove set, but unused variable 'w'
Date: Tue, 7 Jul 2020 14:06:08 -0500 [thread overview]
Message-ID: <20200707190612.97799-10-pierre-louis.bossart@linux.intel.com> (raw)
In-Reply-To: <20200707190612.97799-1-pierre-louis.bossart@linux.intel.com>
From: Lee Jones <lee.jones@linaro.org>
Looks like 'w' has remained unchecked since the driver's inception.
Fixes the following W=1 kernel build warning(s):
sound/soc/ti/omap-mcbsp-st.c: In function ‘omap_mcbsp_st_chgain’:
sound/soc/ti/omap-mcbsp-st.c:145:6: warning: variable ‘w’ set but not used [-Wunused-but-set-variable]
Peter suggested that the whole read can be removed, so that's
been done too.
