ACPI: intel_idle : break dependency between modules
When the system is booted with some cpus offline, the idle driver is not initialized. When a cpu is set online, the acpi code call the intel idle init function. Unfortunately this code introduce a dependency between intel_idle and acpi. This patch is intended to remove this dependency by using the notifier of intel_idle. This patch has the benefit of encapsulating the intel_idle driver and remove some exported functions. Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Srivatsa S.
