Subject: [PATCH net-next 4/4] net: phy: change phy_start_interrupts to phy_request_interrupt

From: Heiner Kallweit <[email-masked]>
Date: Sat, 19 Jan 2019 12:30:05 +0100

Now that we enable the interrupts in phy_start() we don't have to do it
before. Therefore remove enabling interrupts from phy_start_interrupts()
and rename this function to reflect the changed functionality.
