From mboxrd@z Thu Jan 1 00:00:00 1970 From: pi-cheng.chen@linaro.org (Pi-Cheng Chen) Date: Wed, 1 Jul 2015 12:07:27 +0800 Subject: [PATCH] thermal: cpu_cooling: Iterate over all CPUs in clip_cpu mask to get frequency table Message-ID: <1435723647-3354-1-git-send-email-pi-cheng.chen@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org __cpufreq_cooling_register() might fail if some CPU other than first one in clip_cpu mask is present earlier e.g. CPU hotplug. Iterate all CPUs in the mask to handle this case.
