Subject: [PATCH RFC 4/9] thermal/acpi: Move the active trip points to the same array
Date: Tue, 4 Oct 2022 19:26:53 +0200 [thread overview]
Message-ID: <20221004172658.2302511-5-daniel.lezcano@linaro.org> (raw)
In-Reply-To: <20221004172658.2302511-1-daniel.lezcano@linaro.org>
This change does the second pass to move the active trip points in the
thermal trip array.
