If MTK_THERMAL is set to 'm' a mtk_thermal.ko module will be built. I
didn't spot a MODULE_LICENSE() macro in this file. So I think that, if
mtk_thermal.ko gets loaded - I guess through the of_match_table magic -
a warning will be issued and the kernel will be tainted.

(I didn't actually test any of this, so I've wasted your time if I've
overlooked something here.)
