Subject: [PATCH net] net: broadcom/bcmsysport: Fix signedness in
 bcm_sysport_probe()

The "priv->phy_interface" variable is an enum and in this context GCC
will treat it as unsigned so the error handling will never be
triggered.

Fixes: 80105befdb4b ("net: systemport: add Broadcom SYSTEMPORT Ethernet MAC driver")
