From 16da163d874be2581ba639e68cd8568852b97e67 Mon Sep 17 00:00:00 2001 From: dianlujitao Date: Sat, 14 Oct 2017 12:08:10 +0800 Subject: power: msm8998: Support power profiles Author: dianlujitao Date: Sat Oct 14 12:08:10 2017 +0800 power: msm8998: Support power profiles Change-Id: I8a11aa9db00051cfaae650273d980ce5080f6567 Author: dianlujitao Date: Sat Jan 20 22:19:17 2018 +0800 power: msm8998: Fix perf mode switch * Checking a pointer is NULL or not makes no sense, and as a result perf mode cannot be turned off. Fix it by checking the value.
