commit c799fca8baf18d1bbbbad6c3b736eefbde8bdb90 upstream.
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;
