Subject: thermal: testing: Replace sscanf() with kstrtoint()
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e4f87cfcbae03498f0fd1689653cf84126196e14;p=thirdparty%2Flinux.git

thermal: testing: Replace sscanf() with kstrtoint()

Generally, kstrtoint() is preferred to sscanf() in kernel code, so
replace the latter with the former in tt_del_tz() and tt_get_tt_zone().
