net: stmmac: dwmac-meson8b: Fix signedness bug in probe
The "dwmac->phy_mode" is an enum and in this context GCC treats it as an unsigned int so the error handling is never triggered. Fixes: 566e82516253 ("net: stmmac: add a glue driver for the Amlogic Meson 8b / GXBB DWMAC") Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Reviewed-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: David S.
