ASoC: rsnd: ssiu: correct shift bit for ssiu9
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") Signed-off-by: Jiada Wang <jiada_wang@mentor.com> Acked-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
