From 3b455cdc49e8d91e84184e60e01a390c7eb23134 Mon Sep 17 00:00:00 2001 From: Quentin Schulz Date: Tue, 26 Sep 2017 14:52:19 +0200 Subject: [PATCH] iio: adc: sun4i-gpadc-iio: do not fail probing when no thermal DT node Before this patch, forgetting to put a thermal-zones DT node would result in the driver failing to probe. It should be perfectly acceptable to have the driver probe even if no thermal-zones DT is found. However, it shouldn't want to fail if the thermal registering fail for any other reason (waiting for other drivers for example) so check on ENODEV only.
