Subject: [PATCH 4.2.y-ckt 073/305] thermal: fix thermal_zone_bind_cooling_device prototype

4.2.8-ckt2 -stable review patch.  If anyone has any objections, please let me know.

---8<------------------------------------------------------------

From: Arnd Bergmann <arnd@...db.de>

commit c86b3de8c8b02d7e474fdc002c8df533b844524c upstream.

When the prototype for thermal_zone_bind_cooling_device
changed, the static inline wrapper function was left alone,
which in theory can cause build warnings:

I have seen this error in the past:
drivers/thermal/db8500_thermal.c: In function 'db8500_cdev_bind':
drivers/thermal/db8500_thermal.c:78:9: error: too many arguments to function 'thermal_zone_bind_cooling_device'
   ret = thermal_zone_bind_cooling_device(thermal, i, cdev,

while this one no longer shows up, there is no doubt that
the prototype is still wrong, so let's just fix it anyway.
