During system resume: kernel BUG at drivers/base/regmap/regcache.c:347! ... PC is at regcache_sync+0x1c/0x128 LR is at ak4613_resume+0x28/0x34 The ak4613 driver is using a regmap cache sync to restore the configuration of the chip on resume but does not actually define a register cache which means that the resume 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:
