riscv: Fix sparse warning about different address spaces
We did not propagate the __user attribute of the pointers in
__get_kernel_nofault() and __put_kernel_nofault(), which results in
sparse complaining:
>> mm/maccess.c:41:17: sparse: sparse: incorrect type in argument 2 (different address spaces) @@ expected void const [noderef] __user *from @@ got unsigned long long [usertype] * @@
mm/maccess.c:41:17: sparse: expected void const [noderef] __user *from
mm/maccess.c:41:17: sparse: got unsigned long long [usertype] *
So fix this by correctly casting those pointers.
