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")
