Subject: [PATCH v2 4/8] cpufreq: Preserve sysfs min/max request
Date: Fri, 13 Jan 2012 14:59:15 +0200	[thread overview]
Message-ID: <1326459559-5436-5-git-send-email-amiettinen@nvidia.com> (raw)
In-Reply-To: <1326459559-5436-1-git-send-email-amiettinen@nvidia.com>

Store the value received via sysfs as the user_policy
min/max value instead of the currently enforced min/max.
This allows restoring the user min/max values when
constraints on enforced min/max change.
