[alsa-devel] [PATCH] ASoC: fsl: Correct FSL_SAI_CR2_MSEL_MASK definition

[Takashi Iwai]

The bit mask FSL_SAI_CR2_MSEL_MASK is defined as (0xff << 26) and this
obviously overflows the 32bit integer.  Also this clears other bits
than the needed ones (FSL_SAI_CR2_MSEL_XXX) wrongly.

This patch fixes the definition only to mask bits 26 and 27.
