Subject: [PATCH 1/4] cpufreq: schedutil: Initialize sg_cpu->flags to 0
Date: Wed, 13 Dec 2017 15:23:20 +0530	[thread overview]
Message-ID: <763feda6424ced8486b25a0c52979634e6104478.1513158452.git.viresh.kumar@linaro.org> (raw)

Initializing sg_cpu->flags to SCHED_CPUFREQ_RT has no obvious benefit.
The flags field wouldn't be used until the utilization update handler is
called for the first time, and once that is called we will overwrite
flags anyway.

Initialize it to 0.
