Subject: [PATCH v5 5/5] iio: adc: ad7949: use devm managed functions
Date: Sat,  7 Aug 2021 21:56:59 -0400	[thread overview]
Message-ID: <20210808015659.2955443-6-liambeguin@gmail.com> (raw)
In-Reply-To: <20210808015659.2955443-1-liambeguin@gmail.com>

From: Liam Beguin <lvb@xiphos.com>

Switch to devm_iio_device_register to finalize devm migration.
This removes the use for iio_device_unregister() and since
mutex_destroy() is not necessary here, remove it altogether.
