lib/devres.c: fix some sparse warnings
Having a discussion about sparse warnings in the kernel, and that we should clean them up, I decided to pick a random file to do so. This happened to be devres.c which gives the following warnings: CHECK lib/devres.c lib/devres.c:83:9: warning: cast removes address space of expression lib/devres.c:117:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:117:31: expected void [noderef] <asn:2>* lib/devres.c:117:31: got void * lib/devres.c:125:31: warning: incorrect type in return expression (different address spaces) lib/devres.c:125:31: expected void [noderef] <asn:2>* lib/devres.c:125:31: got void * lib/devres.c:136:26: warning: incorrect type in assignment (different address spaces) lib/devres.c:136:26: expected void [noderef] <asn:2>*[assigned] dest_ptr lib/devres.c:136:26: got void * lib/devres.c:226:9: warning: cast removes address space of expression Mostly it's just the use of typecasting to void * without adding __force, or returning ERR_PTR(-ESOMEERR) without typecasting to a __iomem type. I added a helper macro IOMEM_ERR_PTR() that does the typecast to make the code a little nicer than adding ugly typecasts to the code.
