Subject: [PATCH 1/3] iio: accel: adxl313_core: Use devm-managed mutex initialization
Date: Thu, 16 Apr 2026 10:46:29 +0530 [thread overview]
Message-ID: <20260416051631.551250-2-sanjayembedded@gmail.com> (raw)
In-Reply-To: <20260416051631.551250-1-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.
