Assuming that the intention is only to set LEDs active-low that were
previously configured to be active-low, then:

Reviewed-by: Russell King (Oracle) <rmk+kernel@xxxxxxxxxxxxxxx>

It's good that we don't call aqr_phy_led_active_low_set() for every LED
in the .config_init method because we don't know whether the LED
outputs for this PHY are used on SFPs to drive e.g. the SFP LOS pin,
and changing LED settings in such a case could cause incorrect
signalling. If this ever changes, then this code needs to be
conditional on !phy_on_sfp(phydev).

Thanks!
