Subject: [PATCH] ASoC: fsl: Fix refcount leak in imx_sgtl5000_probe
Date: Wed, 11 May 2022 10:58:03 +0400 [thread overview]
Message-ID: <20220511065803.3957-1-linmq006@gmail.com> (raw)
of_find_i2c_device_by_node() takes a reference,
In error paths, we should call put_device() to drop
the reference to aviod refount leak.
Fixes: 81e8e4926167 ("ASoC: fsl: add sgtl5000 clock support for imx-sgtl5000")
