Subject: [PATCH] soc: qcom: aoss: Fix missing put_device call in qmp_get
Date: Sat, 8 Jan 2022 09:59:31 +0000 [thread overview]
Message-ID: <20220108095931.21527-1-linmq006@gmail.com> (raw)
The reference taken by 'of_find_device_by_node()' must be released when
not needed anymore.
Add the corresponding 'put_device()' in the error handling paths.
Fixes: 8c75d585b931 ("soc: qcom: aoss: Expose send for generic usecase")
