Subject: [PATCH] leds: trigger: netdev: fix handling on interface rename
|
|
|
|
The NETDEV_CHANGENAME code is not "unneeded" like it is stated in commit
|
|
4cb6560514fa ("leds: trigger: netdev: fix refcnt leak on interface
|
|
rename").
|
|
|
|
The event was accidentally misinterpreted equivalent to
|
|
NETDEV_UNREGISTER, but should be equivalent to NETDEV_REGISTER.
|
|
|
|
This was the case in the original code from the openwrt project.
|
|
|
|
Otherwise, you are unable to set netdev led triggers for (non-existent)
|
|
netdevices, which has to be renamed. This is the case, for example, for
|
|
ppp interfaces in openwrt.
