Subject: leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on dev rename
From: Christian Marangi <ansuelsmth@xxxxxxxxx>
commit cee4bd16c3195a701be683f7da9e88c6e11acb73 upstream.
Dev can be renamed also while up for supported device. We currently
wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME
event.
Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
correctly set the NETDEV_LED_MODE_LINKUP bit.
