Subject: [PATCH v3 10/10] cpufreq: governor: Drop cpu argument from dbs_check_cpu()
Date: Sat, 06 Feb 2016 13:50:24 +0100 [thread overview]
Message-ID: <3908268.r5qEEZP0qG@vostro.rjw.lan> (raw)
In-Reply-To: <2367498.ClbHvSsNAg@vostro.rjw.lan>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Since policy->cpu is always passed as the second argument to
dbs_check_cpu(), it is not really necessary to pass it, because
the function can obtain that value via its first argument just fine.

Changes from v2:
- Rebase on top of https://patchwork.kernel.org/patch/8241231/
and on the v3 of [8/10] without [9/10].
