[PATCH 3.19 161/177] ASoC: omap-pcm: Correct dma mask

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2015-03-16 14:19:57
Also in: lkml

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

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

From: Peter Ujfalusi <redacted>

commit d51199a83a2cf82a291d19ee852c44caa511427d upstream.

DMA_BIT_MASK of 64 is not valid dma address mask for OMAPs, it should be
set to 32.
The 64 was introduced by commit (in 2009):
a152ff24b978 ASoC: OMAP: Make DMA 64 aligned

But the dma_mask and coherent_dma_mask can not be used to specify alignment.

Fixes: a152ff24b978 (ASoC: OMAP: Make DMA 64 aligned)
