   4 Subject: [PATCH 1/5] leds: trigger: netdev: Recheck NETDEV_LED_MODE_LINKUP on
   5  dev rename
   6
   7 Dev can be renamed also while up for supported device. We currently
   8 wrongly clear the NETDEV_LED_MODE_LINKUP flag on NETDEV_CHANGENAME
   9 event.
  10
  11 Fix this by rechecking if the carrier is ok on NETDEV_CHANGENAME and
  12 correctly set the NETDEV_LED_MODE_LINKUP bit.

  14 Fixes: 5f820ed52371 ("leds: trigger: netdev: fix handling on interface rename")
