[PATCH 6.1 386/885] leds: led-core: Fix refcount leak in of_led_get()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Miaoqian Lin <linmq006@xxxxxxxxx>

[ Upstream commit da1afe8e6099980fe1e2fd7436dca284af9d3f29 ]

class_find_device_by_of_node() calls class_find_device(), it will take
the reference, use the put_device() to drop the reference when not need
anymore.

Fixes: 699a8c7c4bd3 ("leds: Add of_led_get() and led_put()")
