Subject: [PATCH] net: free_netdev: exit earlier if dummy
|
|
|
|
For dummy devices, exit earlier at free_netdev() instead of executing
|
|
the whole function. This is necessary, because dummy devices are
|
|
special, and shouldn't have the second part of the function executed.
|
|
|
|
Otherwise reg_state, which is NETREG_DUMMY, will be overwritten and
|
|
there will be no way to identify that this is a dummy device. Also, this
|
|
device do not need the final put_device(), since dummy devices are not
|
|
registered (through register_netdevice()), where the device reference is
|
|
increased (at netdev_register_kobject()/device_add()).
