The wm8940 driver is using a regmap cache sync to restore the configuration of the chip when switching from OFF to STANDBY, but does not actually define a register cache which means that the restore is never going to work and we trigger asserts in regmap. Fix this by enabling caching. Based on commit d3030d11 ("ASoC: ak4642: Enable cache usage to fix crashes on resume") by Mark Brown <broonie@kernel.org>. Signed-off-by:
