    Subject[PATCH 3.5 35/90] ASoC: wm8962: Turn on regcache_cache_only before disabling regulator
    Date
    3.5.7.27 -stable review patch.  If anyone has any objections, please let me know.

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

    From: Nicolin Chen <b42378@freescale.com>

    commit 50bfcf2df2fadf77e143d6099150e6fa7ef4d78c upstream.

    It's safer to turn on regcache_cache_only before disabling regulator since
    the driver will turn off the regcache_cache_only after enabling regulator.

    If we remain cache_only false, some command like 'amixer cset' would get
    failure if being run before wm8962_resume().
