Subject: [PATCH v2 1/4] iio: adc: at91_adc: use of_device_get_match_data() helper
Date: Wed, 30 Sep 2020 09:00:05 +0300 [thread overview]
Message-ID: <20200930060008.42134-2-alexandru.ardelean@analog.com> (raw)
In-Reply-To: <20200930060008.42134-1-alexandru.ardelean@analog.com>
This is a small tidy-up. The of_device_get_match_data() helper retrieves
the driver data from the OF table, without needed to explicitly know the
table variable (since it can retrieve it from the driver object).
