Subject: [PATCH 3/5] thermal/drivers/acpi: Use hot and critical ops
Date: Thu, 10 Dec 2020 13:15:12 +0100 [thread overview]
Message-ID: <20201210121514.25760-3-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20201210121514.25760-1-daniel.lezcano@linaro.org>
The acpi driver wants to do a netlink notification in case of a hot or
critical trip point. Implement the corresponding ops to be used for
the thermal zone and use them instead of the notify ops.
