Physically reading and writing controls to/from the DSP are handled by two low level functions (wm_coeff_{write|read}_control, these currently take in a snd_kcontrol pointer but immediately pull out a wm_coeff_ctl pointer from the private data. These functions don't handle the kcontrols at all they just shuttle data to and from the chip and all the call sites have a wm_coeff_ctl pointer available. This patch just passes the wm_coeff_ctl pointer straight into these functions.
