Subject: [PATCH V2 2/6] Thermal: make sure cpufreq cooling register after cpufreq driver
Date: Wed, 24 Oct 2012 19:58:16 +0800 [thread overview]
Message-ID: <1351079900-32236-3-git-send-email-hongbo.zhang@linaro.com> (raw)
In-Reply-To: <1351079900-32236-1-git-send-email-hongbo.zhang-68IGFXMjmZ7QT0dZR+AlfA@public.gmane.org>
From: "hongbo.zhang" <hongbo.zhang-68IGFXMjmZ7QT0dZR+AlfA@public.gmane.org>
The cpufreq works as a cooling device, so the cooling layer should check if the
cpufreq driver is initialized or not.
