[ Upstream commit 671f8204b12fae98dcc6fc5a5703a5c62cbea187 ]
Convert the sisr and sisr2 variable types to u32 to avoid the following sparse warnings:
sound/soc/fsl/fsl_ssi.c:391:42: warning: incorrect type in argument 3 (different base types) sound/soc/fsl/fsl_ssi.c:391:42: expected unsigned int *val sound/soc/fsl/fsl_ssi.c:391:42: got restricted __be32 *<noident> sound/soc/fsl/fsl_ssi.c:393:17: warning: restricted __be32 degrades to integer sound/soc/fsl/fsl_ssi.c:393:15: warning: incorrect type in assignment (different base types) sound/soc/fsl/fsl_ssi.c:393:15: expected restricted __be32 [usertype] sisr2 sound/soc/fsl/fsl_ssi.c:393:15: got unsigned int sound/soc/fsl/fsl_ssi.c:396:50: warning: incorrect type in argument 3 (different base types) sound/soc/fsl/fsl_ssi.c:396:50: expected unsigned int [unsigned] val sound/soc/fsl/fsl_ssi.c:396:50: got restricted __be32 [usertype] sisr2 sound/soc/fsl/fsl_ssi.c:398:42: warning: incorrect type in argument 2 (different base types) sound/soc/fsl/fsl_ssi.c:398:42: expected unsigned int [unsigned] [usertype] sisr sound/soc/fsl/fsl_ssi.c:398:42: got restricted __be32 [addressable] [usertype] sisr
In other places where regmap_read() is used a u32 variable is passed to store the register read value, so do the same here as well.
regmap API already takes care of endianness, so the usage of u32 is safe.
