Static analysis reports this problem
igc_main.c:4944:20: warning: The left operand of '&' is a garbage value if (!(phy_data & SR_1000T_REMOTE_RX_STATUS) && ~~~~~~~~ ^
phy_data is set by the call to igc_read_phy_reg() only if there is a read_reg() op, else it is unset and a 0 is returned. Change the return to -EOPNOTSUPP.
