2018-11-23net: hinic: fix null pointer dereference on pointer hwdevColin Ian King1-2/+4
Pointer hwdev is being dereferenced when declaring hwif , however, later on hwdev is being null checked, hence we have dereference before null check error. Fix this by assigning hwif and pdef only once hwdev has been null checked. Detected by CoverityScan, CID#1485581 ("Dereference before null check") Fixes: 4a61abb100c8 ("net-next/hinic:add rx checksum offload for HiNIC") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: David S.
