[PATCH v2 1/4] iio: adc: at91_adc: use of_device_get_match_data() helper

From: Alexandru Ardelean
Date: Wed Sep 30 2020 - 01:56:09 EST


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).
