Subject: [PATCH] net: phy: move LED polarity to phy_init_hw
|
|
|
|
Some PHY reset the polarity on reset and this cause the LED to
|
|
malfunction as LED polarity is configured only when LED is
|
|
registered.
|
|
|
|
To better handle this, move the LED polarity configuration in
|
|
phy_init_hw to reconfigure it after PHY reset.
