Stephen Boyd e3b7868435 coresight: STM: Clean up __iomem type usage ... The casting and other things here is odd, and causes sparse to complain: drivers/hwtracing/coresight/coresight-stm.c:279:35: warning: incorrect type in argument 1 (different address spaces) drivers/hwtracing/coresight/coresight-stm.c:279:35: expected void [noderef] <asn:2>*addr drivers/hwtracing/coresight/coresight-stm.c:279:35: got struct stm_drvdata *drvdata drivers/hwtracing/coresight/coresight-stm.c:327:17: warning: incorrect type in argument 2 (different address spaces) drivers/hwtracing/coresight/coresight-stm.c:327:17: expected void volatile [noderef] <asn:2>*addr drivers/hwtracing/coresight/coresight-stm.c:327:17: got void *addr drivers/hwtracing/coresight/coresight-stm.c:330:17: warning: incorrect type in argument 2 (different address spaces) drivers/hwtracing/coresight/coresight-stm.c:330:17: expected void volatile [noderef] <asn:2>*addr drivers/hwtracing/coresight/coresight-stm.c:330:17: got void *addr drivers/hwtracing/coresight/coresight-stm.c:333:17: warning: incorrect type in argument 2 (different address spaces) drivers/hwtracing/coresight/coresight-stm.c:333:17: expected void volatile [noderef] <asn:2>*addr drivers/hwtracing/coresight/coresight-stm.c:333:17: got void *addr >From what I can tell, we don't really need to treat ch_addr as anything besides a pointer, and we can just do pointer math instead of ORing in the bits of the offset and achieve the same thing. Also, we were passing a drvdata pointer to the coresight_timeout() function, but we really wanted to pass the address of the register base. Luckily the base is the first member of the structure, so everything works out, but this is quite unsafe if we ever change the structure layout. Clean this all up so sparse stops complaining on this code.
