[alsa-devel] [PATCH 0/9] ASoC: codecs: Fix register cache incoherencies

[Lars-Peter Clausen]

The multi-component patch(commit f0fba2ad1) introduced a generic register cache
framework. Most of the drivers where converted to use this new framework. But
there are also some drivers now which use a mixture of their own register cache
and the generic register cache.
Thus these end up with two from each other incoherent register caches, which can
lead to undefined behaviour.
This patch series tries to fix these drivers by converting them to always use
the generic register cache framework instead of their own.

There are also quite a few drivers left, which do not use their own register
cache, but still have a field for it in their private device structure. The
first patch of this series addresses those drivers and removes the unused
register cache arrays from their private device structs.

Please note, these patches, with the exception of wm8753, were only compile
tested.
