[PATCH RFC net-next] net: phy: always set polarity_modes if op is supported

From: Daniel Golle
Date: Fri Oct 04 2024 - 11:59:03 EST


Some PHYs drive LEDs active-low by default and polarity needs to be
configured in case the 'active-low' property is NOT set.
One way to achieve this without introducing an additional 'active-high'
property would be to always call the led_polarity_set operation if it
is supported by the phy driver.
