The multi-component patch(commit f0fba2ad1) moved the allocation of the register cache from the driver to the ASoC core. Most drivers where adjusted to this, but the wm8904 driver still uses its own register cache for its private functions, while functions from the ASoC core use the generic cache. Thus we end up with two from each other incoherent caches, which can lead to undefined behaviour. This patch fixes the issue by changing the wm8904 driver to use the generic register cache in its private functions.
