net: usb: asix: Fix less than zero comparison of a u16
The comparison of the u16 priv->phy_addr < 0 is always false because phy_addr is unsigned. Fix this by assigning the return from the call to function asix_read_phy_addr to int ret and using this for the less than zero error check comparison. Addresses-Coverity: ("Unsigned compared against 0") Fixes: e532a096be0e ("net: usb: asix: ax88772: add phylib support") Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: David S.
