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

[Lee Jones]

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 âomap_mcbsp_st_chgainâ:
 sound/soc/ti/omap-mcbsp-st.c:145:6: warning: variable âwâ set but not used [-Wunused-but-set-variable]
