[RFC,v2,2/9] thermal: Eliminate an always-false condition

Commit Message

Andrzej Pietrasiewicz April 14, 2020, 6 p.m. UTC

This driver provides a non-NULL "devdata" argument for
thermal_zone_device_register(). Thermal core never sets it to NULL
afterwards, so checking for its being NULL in this driver makes no sense.
