[alsa-devel] [PATCH 2/2] ASoC: wm8753: Drop wm8753_writeable function

[Axel Lin]

When .max_register is set and .writeable_reg is not implement, registers
between 0 and .max_register are writeable. This is the same as current
implementation of wm8753_writeable(), so just drop implementation for
.writeable_reg callback.
