    Subject[PATCH 3.16.y-ckt 119/128] ASoC: arizona: Fix bclk for sample rates that are multiple of 4kHz
    Date
    3.16.7-ckt23 -stable review patch.  If anyone has any objections, please let me know.

    ---8<------------------------------------------------------------

    From: Nikesh Oswal <Nikesh.Oswal@cirrus.com>

    commit e73694d871867cae8471d2350ce89acb38bc2b63 upstream.

    For a sample rate of 12kHz the bclk was taken from the 44.1kHz table as
    we test for a multiple of 8kHz. This patch fixes this issue by testing
    for multiples of 4kHz instead.
