Subject: [PATCH 8/8] firmware: imx: scu: Use devm_mutex_init
Date: Tue, 14 Oct 2025 12:54:45 +0800 [thread overview]
Message-ID: <20251014-imx-firmware-v1-8-ba00220613ca@nxp.com> (raw)
In-Reply-To: <20251014-imx-firmware-v1-0-ba00220613ca@nxp.com>
In normal case, there is no need to invoke mutex_destroy in error path,
but it is useful when CONFIG_DEBUG_MUTEXES, so use devm_mutex_init().
