> Commit a5afc1678044 ("net: phy: mscc: add support for VSC8584 PHY")
> introduced a call to 'phy_write' storing its return value to a variable
> called 'ret'. But 'ret' never was checked for a possible error being
> returned, and hence was not used at all. Fix this by checking the return
> value and exiting the function if an error was returned.
