This reverts commit763658b99f. This is a preparation change for merging android-4.19.14 into msm-4.19 branch. It is needed to resolve conflicts caused by merging upstream change [1]. [1] was fully discarded in upmerge [2]. Now Tech team (Ram Chandrasekar) decided to pick up the change. [1] ANDROID: thermal: cpu_cooling: Migrate to using the EM framework [2]4ac13bd161Merge remote-tracking branch 'origin_4.19/tmp-0567d2f' into msm-4.19 Change-Id: Ia9971afff379228a55652f8d10e77b14cc5afa3b Signed-off-by: Ivaylo Georgiev <irgeorgiev@codeaurora.org>
