    Subject[PATCH 21/28] ASoC: ti: omap-mcbsp-st: Remove set, but unused variable 'w'
    Date
    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]
