Probably sparse just doesn't pay attention to const, but shouldn't the definitions of __chk_user_ptr and __chk_io_ptr be extern void __chk_user_ptr(const void __user *); extern void __chk_io_ptr(const void __iomem *); instead of extern void __chk_user_ptr(void __user *); extern void __chk_io_ptr(void __iomem *); ?
