    ASoC: codecs: wm8753: Fix register cache incoherency · 776065e3
    Lars-Peter Clausen authored
    The multi-component patch(commit f0fba2ad) moved the allocation of the
    register cache from the driver to the ASoC core. Most drivers where adjusted to
    this, but the wm8753 driver still uses its own register cache for its
    private functions, while functions from the ASoC core use the generic cache.
    Furthermore the generic cache uses zero-based numbering while the wm8753 cache
    uses one-based numbering.
    Thus we end up with two from each other incoherent caches, which leads to undefined
    behaviour and crashes.
    This patch fixes the issue by changing the wm8753 driver to use the generic
    register cache in its private functions.
