Subject: [PATCH v1 2/3] iio: magnetometer: yamaha-yas530: Use devm_mutex_init() for mutex initialization
Date: Fri, 8 May 2026 08:08:34 +0200 [thread overview]
Message-ID: <20260508060958.1086818-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20260508060958.1086818-1-andriy.shevchenko@linux.intel.com>
Use devm_mutex_init() since it brings some benefits when
CONFIG_DEBUG_MUTEXES is enabled.
