net/cxgb4: Check the return from t4_query_params properly
Positive return values are also failures that don't set val, although this probably can't happen. Fixes gcc 10 warning: drivers/net/ethernet/chelsio/cxgb4/t4_hw.c: In function ‘t4_phy_fw_ver’: drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:3747:14: warning: ‘val’ may be used uninitialized in this function [-Wmaybe-uninitialized] 3747 | *phy_fw_ver = val; Fixes: 01b6961410b7 ("cxgb4: Add PHY firmware support for T420-BT cards") Signed-off-by: Jason Gunthorpe <jgg@mellanox.com> Signed-off-by: David S.
