From b596d895fa2957e136a6b398b97b06bd42b51291 Mon Sep 17 00:00:00 2001 From: Matthias Kaehlcke Date: Fri, 3 Aug 2018 13:05:11 -0700 Subject: [PATCH] PM / devfreq: Make update_devfreq() public Currently update_devfreq() is only visible to devfreq governors outside of devfreq.c. Make it public to allow drivers that adjust devfreq policies to cause a re-evaluation of the frequency after a policy change.
