Subject: [PATCH 10/11] iio: adc: ad7124: Use devm_ managed calls for all of probe() + drop remove()
Date: Mon, 10 May 2021 15:55:22 +0300 [thread overview]
Message-ID: <20210510125523.1271237-11-aardelean@deviqon.com> (raw)
In-Reply-To: <20210510125523.1271237-1-aardelean@deviqon.com>
From: Jonathan Cameron <Jonathan.Cameron@huawei.com>
As not many steps were not already devm_ managed, use
devm_add_action_or_reset() to handle the rest.
This also uses the new devm_ad_sd_setup_buffer_and_trigger() function.
