[PATCH 6/6] leds: led-class: mark classdev as unregistering early

[James Ye]

The classdev was marked as unregistering after disabling the trigger.
Disabling the trigger attempts to turn the LED off, and the device may
already be inaccessible. This generates a "Setting an LED's brightness
failed" log, which is avoided by changing this order.
