I think you'll have to revert both WM5100 patches that came in with v3.2.3:

78fd75340768980ce6ca646106762a6928289e0c ASoC: Don't go through cache 
when applying WM5100 rev A updates
11a17e56ac9c607c6eaecf64b618cd17c828ade0 ASoC: Mark WM5100 register map 
cache only when going into BIAS_OFF

Adding the dependent patch bd132ec585c498ee27d7eedf8569703606743928 does 
allow the compile to succeed. But, as you pointed out, its a huge patch 
and doesn't really qualify for stable.
