Subject: pass: thermal: Fix possible null deference in thermal_free()
X-Git-Tag: accepted/tizen/unified/20230808.170202^0
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=refs%2Fchanges%2F55%2F296955%2F2;p=platform%2Fcore%2Fsystem%2Fpass.git

pass: thermal: Fix possible null deference in thermal_free()

When there is no thermal scenario, thermal can not be initialized
and g_thermal is null. Exiting pass from the status, in
thermal_free(), there is null deference. Fix the possible null
deference.
