From mboxrd@z Thu Jan 1 00:00:00 1970 From: daniel.lezcano@linaro.org (Daniel Lezcano) Date: Thu, 10 Apr 2014 11:55:33 +0200 Subject: [PATCH V4 02/20] ARM: exynos: cpuidle: Use cpuidle_register In-Reply-To: <1397123751-1957-1-git-send-email-daniel.lezcano@linaro.org> References: <1397123751-1957-1-git-send-email-daniel.lezcano@linaro.org> Message-ID: <1397123751-1957-3-git-send-email-daniel.lezcano@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Use the cpuidle generic function 'cpuidle_register'. That saves us from some extra lines of code and unneeded variables. A side effect of this change is a bug fix where before the cpuidle driver was registered for each_online_cpu and now it is for each_possible_cpu.
