Hello Iwai-san,

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.
An identical fix was included in the Commit c3ecef21c3f26bf47 (ASoC: fsl_sai: add sai master mode support) by Zidan Wang. And it's already in the linux-next tree.
Ah good, thanks. I hope I would have received pulls for ASoC changes more often...
Takashi
Thank you Nicolin
