Subject: [PATCH v7 09/11] thermal: core: Stop polling DISABLED thermal devices
Date: Mon, 29 Jun 2020 14:29:23 +0200 [thread overview]
Message-ID: <20200629122925.21729-10-andrzej.p@collabora.com> (raw)
In-Reply-To: <20200629122925.21729-1-andrzej.p@collabora.com>
Polling DISABLED devices is not desired, as all such "disabled" devices
are meant to be handled by userspace. This patch introduces and uses
should_stop_polling() to decide whether the device should be polled or not.
