[alsa-devel] [PATCH 4/6] ASoC: cs4265: Mark chip ID register as volatile

[Charles Keepax]

Mark the chip ID register as volatile, the current code does work as
without a default value regmap will read from the hardware the first
time, however, this makes it more explicit that this register should be
read from the hardware.
