net: fixup address-space warnings in compat_mc_{get,set}sockopt()
Add __user attributes in some of the casts in this function to avoid the following sparse warnings: net/compat.c:592:57: warning: cast removes address space of expression net/compat.c:592:57: warning: incorrect type in initializer (different address spaces) net/compat.c:592:57: expected struct compat_group_req [noderef] <asn:1>*gr32 net/compat.c:592:57: got void *<noident> net/compat.c:613:65: warning: cast removes address space of expression net/compat.c:613:65: warning: incorrect type in initializer (different address spaces) net/compat.c:613:65: expected struct compat_group_source_req [noderef] <asn:1>*gsr32 net/compat.c:613:65: got void *<noident> net/compat.c:634:60: warning: cast removes address space of expression net/compat.c:634:60: warning: incorrect type in initializer (different address spaces) net/compat.c:634:60: expected struct compat_group_filter [noderef] <asn:1>*gf32 net/compat.c:634:60: got void *<noident> net/compat.c:672:52: warning: cast removes address space of expression net/compat.c:672:52: warning: incorrect type in initializer (different address spaces) net/compat.c:672:52: expected struct compat_group_filter [noderef] <asn:1>*gf32 net/compat.c:672:52: got void *<noident> Signed-off-by: Ben Dooks <ben.dooks@codethink.co.uk> Signed-off-by: David S.
