Subject: thermal: int3403: Delete a check before thermal_zone_device_unregister()
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=931b9c86d9a518b1374157f103168fb787e6560e;p=openwrt%2Fstaging%2Fblogic.git

thermal: int3403: Delete a check before thermal_zone_device_unregister()

The thermal_zone_device_unregister() function tests whether its argument
is NULL and then returns immediately. Thus the test around the call
is not needed.

This issue was detected by using the Coccinelle software.
