[alsa-devel] [PATCH] ASoC: rsnd: ssiu: correct shift bit for ssiu9

[Kuninori Morimoto]

Hi Jiada

> Currently "0xf << 36" is used to
> clear SSIU-9 internal buffer state, which overflows 32-bit value
> according to user reference manual, it is always bit4 ~ bit7
> of SSI_SYS_STATUS[1,3,5,7] registers indicate
> SSIU-9's buffer state, so "0xf << 4" should be used.
> 
> This patch fix incorrect shifting issue in SSIU-9 case
> 
> Fixes: commit b7169ddea2f2 ("ASoC: rsnd: remove RSND_REG_ from rsnd_reg")
