Subject: [PATCH v2 8/9] thermal/core: Remove thermal_zone_set_trips()
Date: Thu, 10 Nov 2022 07:24:59 -0800 [thread overview]
Message-ID: <20221110152500.3032655-9-linux@roeck-us.net> (raw)
In-Reply-To: <20221110152500.3032655-1-linux@roeck-us.net>
Since no callers of thermal_zone_set_trips() are left, remove the function.
Document __thermal_zone_set_trips() instead. Explicitly state that the
thermal zone lock must be held when calling the function, and that the
pointer to the thermal zone must be valid.
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
