    Subject[ 023/122] ASoC: wm8962: Redo early init of the part on resume
    Date
    From: Greg KH <gregkh@linuxfoundation.org>

    3.5-stable review patch. If anyone has any objections, please let me know.

    ------------------

    From: Mark Brown <broonie@opensource.wolfsonmicro.com>

    commit e4dd76788c7e5b27165890d712c8c4f6f0abd645 upstream.

    Ensure robust startup of the part by going through the reset procedure
    prior to resyncing the full register cache, avoiding potential intermittent
    faults in some designs.
