[PATCH net-next] net: phy: Added IRQ print to phylink_bringup_phy()

From: Florian Fainelli
Date: Sun Jan 12 2020 - 12:35:45 EST


The information about the PHY attached to the PHYLINK instance is useful
but is missing the IRQ prints that phy_attached_info() adds.
phy_attached_info() is a bit long and it would not be possible to use
phylink_info() anyway.
