[PATCH] mfd: wm8994: declare dc servo register for wm8958 as volatile

2014-08-13 Thread Nikesh Oswal
DC Servo register 57h holds the DC offset value after the hardware has completed the DC Servo Correction, so declare this register as volatile because it is changed by the hardware. Signed-off-by: Nikesh Oswal --- drivers/mfd/wm8994-regmap.c |1 + include/linux/mfd/wm8994/registers.
