Subsystem:

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.
