Subject: [PATCH] iio: adc: aspeed: Fix refcount leak in aspeed_adc_set_trim_data
Date: Mon, 16 May 2022 11:52:02 +0400 [thread overview]
Message-ID: <20220516075206.34580-1-linmq006@gmail.com> (raw)
of_find_node_by_name() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add missing of_node_put() to avoid refcount leak.
Fixes: d0a4c17b4073 ("iio: adc: aspeed: Get and set trimming data.")
