Subject: [PATCH v2 1/8] iio: accel: adxl313_core: Use devm-managed mutex initialization
Date: Fri, 17 Apr 2026 18:19:17 +0530 [thread overview]
Message-ID: <20260417124924.353189-2-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260417124924.353189-1-sanjayembedded@gmail.com>
From: Sanjay Chitroda <sanjayembeddedse@gmail.com>
Use devm_mutex_init() to tie the mutex lifetime to the device and
improve debugging when CONFIG_DEBUG_MUTEXES is enabled.
