Subject: [PATCH v3 11/12] iio: adc: ad7124: Use devm_ managed calls for all of probe() + drop remove()
Date: Wed, 12 May 2021 20:49:13 +0300	[thread overview]
Message-ID: <20210512174914.10549-12-aardelean@deviqon.com> (raw)
In-Reply-To: <20210512174914.10549-1-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.
