Subject[PATCH] thermal/core: Fix lockdep_assert() warning
Date
The function thermal_zone_device_is_enabled() must be called with the
thermal zone lock held. In the resume path, it is called without.

As the thermal_zone_device_is_enabled() is also checked in
thermal_zone_device_update(), do the check in resume() function is
pointless, except for saving an extra initialization which does not
hurt if it is done in all the cases.
