[PATCH v2] drivers/thermal: optimize the for circle to run a bit fast

From: Bernard Zhao
Date: Mon Oct 26 2020 - 21:47:25 EST


Function thermal_zone_device_register, in the for circle, if the
first if branch set the count bit in tz->trips_disabled, there is
no need to set in the other if branch again.
This change is to make the code run a bit fast and readable.
