Subject: [035/105] ASoC: imx: fix burstsize for DMA
2.6.38-stable review patch. If anyone has any objections, please let us know.
------------------
From: Wolfram Sang <w.sang@...gutronix.de>
commit e1bb31b444668bc957c337d33803db7cb3330745 upstream.
SSI counts in words, the DMA engine in bytes. (Wrong) factor got removed
in bf974a0 (ASoC i.MX: switch to new DMA api).
