Summary
leds: trigger: Unregister sysfs attributes before calling deactivate()
Details

In the Linux kernel, the following vulnerability has been resolved:

leds: trigger: Unregister sysfs attributes before calling deactivate()

Triggers which have trigger specific sysfs attributes typically store related data in trigger-data allocated by the activate() callback and freed by the deactivate() callback.

Calling deviceremovegroups() after calling deactivate() leaves a window where the sysfs attributes show/store functions could be called after deactivation and then operate on the just freed trigger-data.

Move the deviceremovegroups() call to before deactivate() to close this race window.

This also makes the deactivation path properly do things in reverse order of the activation path which calls the activate() callback before calling deviceaddgroups().
