Subject: [PATCH] thermal: bcm2835: enable hwmon explicitly
Date: Sun, 21 Oct 2018 23:58:48 +0200
Patch-mainline: v5.0-rc1
Git-commit: d56c19d07e0bc3ceff366a49b7d7a2440c967b1b
References: bsc#1108468

From: Matthias Brugger <mbrugger@suse.com>

By defaul of-based thermal driver do not enable hwmon.
This patch does this explicitly, so that the temperature can be read
through the common hwmon sysfs.
