virtio_pmem: fix sparse warning
This patch fixes below sparse warning related to __virtio type in virtio pmem driver. This is reported by Intel test bot on linux-next tree. nd_virtio.c:56:28: warning: incorrect type in assignment (different base types) nd_virtio.c:56:28: expected unsigned int [unsigned] [usertype] type nd_virtio.c:56:28: got restricted __virtio32 nd_virtio.c:93:59: warning: incorrect type in argument 2 (different base types) nd_virtio.c:93:59: expected restricted __virtio32 [usertype] val nd_virtio.c:93:59: got unsigned int [unsigned] [usertype] ret Reported-by: kbuild test robot <lkp@intel.com> Signed-off-by: Pankaj Gupta <pagupta@redhat.com> Acked-by: Michael S.
