From: Lars-Peter Clausen <lars <at> metafoo.de>
Subject: [PATCH 0/9 v2] ASoC: codecs: Fix register cache incoherencies
Newsgroups: gmane.linux.alsa.devel
Date: Tuesday 28th December 2010 20:37:54 UTC (over 6 years ago)
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 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 anymore, 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.

Changes since v1:
	* rebased against 2.6.37-rc7
	* correct commit message
	* more straight forward conversion in the wm8753 patch (there will be a
	  followup patch for cleanps)
