Subject: [13/89] ASoC: Mark WM5100 register map cache only when going into BIAS_OFF
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broonie@...nsource.wolfsonmicro.com>
commit e53e417331c57b9b97e3f8be870214a02c99265c upstream.
Writing to the registers won't work if we do actually manage to hit a fully
powered off state.
