Subject: [PATCH 2/3] iio: adc: meson-saradc: use of_device_get_match_data
Date: Sun, 23 Sep 2018 00:21:01 +0200	[thread overview]
Message-ID: <20180922222102.12023-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20180922222102.12023-1-martin.blumenstingl@googlemail.com>

This simplifies our _probe function by using of_device_get_match_data
instead of open-coding it. No functional changes.
