Subject: [PATCH 071/135] net: cavium: liquidio: fix check for in progress flag
[ Upstream commit 19a6d156a7bd080f3a855a40a4a08ab475e34b4a ]
smatch detected a suspicious looking bitop condition:
drivers/net/ethernet/cavium/liquidio/lio_main.c:2529
handle_timestamp() warn: suspicious bitop condition
(skb_shinfo(skb)->tx_flags | SKBTX_IN_PROGRESS is always non-zero,
so the logic is definitely not correct. Use & to mask the correct
bit.
