#1319539 — [PATCH 4.1 054/127] ASoC: arizona: Fix bclk for sample rates that are multiple of 4kHz

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

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

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.
