The sparse tool complains as follows:
sound/soc/fsl/imx-card.c:121:27: warning:
symbol 'ak4458_fs_mul' was not declared. Should it be static?
sound/soc/fsl/imx-card.c:138:31: warning:

sound/soc/fsl/imx-card.c:166:27: warning:

sound/soc/fsl/imx-card.c:180:31: warning:
symbol 'ak5558_tdm_fs_mul' was not declared. Should it be static?
Those symbols are not used outside of imx-card.c, so marks
them static.
