Subject: [PATCH v1 3/3] iio: adc: bcm_iproc_adc: use devm-managed mutex initialization
Date: Tue, 25 Aug 2026 22:51:55 +0530 [thread overview]
Message-ID: <20260825172155.250484-4-mdshahid03@gmail.com> (raw)
In-Reply-To: <20260825172155.250484-1-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.
