Subject: [PATCH v7 08/11] thermal: Explicitly enable non-changing thermal zone devices
Date: Mon, 29 Jun 2020 14:29:22 +0200
Message-ID: <20200629122925.21729-9-andrzej.p@collabora.com> (raw)
In-Reply-To: <20200629122925.21729-1-andrzej.p@collabora.com>

Some thermal zone devices never change their state, so they should be
always enabled.
