ASoC: fsl: Fix lockups with recent cache changes (f26b3b2a) · Commits · 戴 / test

The recent series of changes to the caching in the SSI driver have caused a number of problems to appear in some test systems. These are still not fully understood but we're coming up to the merge window so for now let's revert commit (ASoC: fsl_ssi: Remove .num_reg_defaults_raw from regmap_config) as backing that out seems to resolve the problem on affected systems.
