[PATCH 2/3] pinctrl: single: fix pcs_disable with bits_per_mux

From: Tomi Valkeinen
Date: Thu Nov 28 2013 - 06:30:42 EST


pcs_enable() uses vals->mask instead of pcs->fmask when bits_per_mux is
enabled. However, pcs_disable() always uses pcs->fmask.

Fix pcs_disable() to use vals->mask with bits_per_mux.
