Subject: [PATCH v2 4/5] iio: adc: bcm_iproc_adc: use devm-managed mutex initialization
Date: Sun, 30 Aug 2026 22:39:17 +0530	[thread overview]
Message-ID: <20260830170919.470974-5-mdshahid03@gmail.com> (raw)
In-Reply-To: <20260830170919.470974-1-mdshahid03@gmail.com>

From: Mohammad Shahid <mdshahid03@gmail.com>

Use devm_mutex_init() to tie the mutex lifetime to the device and
improve debugging when CONFIG_DEBUG_MUTEXES is enabled.
