Date: Mon, 25 Jan 2016 15:16:07 +0530 From: "Gautham R. Shenoy" <ego@...ux.vnet.ibm.com> To: "Rafael J. Wysocki" <rjw@...ysocki.net>, Viresh Kumar <viresh.kumar@...aro.org>, linux-pm@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Shilpasri G Bhat <shilpa.bhat@...ux.vnet.ibm.com>, Juri Lelli <juri.lelli@....com>, "Gautham R. Shenoy" <ego@...ux.vnet.ibm.com> Subject: [PATCH] cpufreq: Use list_is_last() to check last entry of the policy list Currently next_policy() explicitly checks if a policy is the last policy in the cpufreq_policy_list. Use the standard list_is_last primitive instead. Cc: Viresh Kumar <viresh.kumar@...aro.org> Signed-off-by: Gautham R.
