cpufreq: Remove unnecessary use of policy->shared_type
policy->shared_type field was added only for SoCs with ACPI support: commit 3b2d99429e3386b6e2ac949fc72486509c8bbe36 Author: Venkatesh Pallipadi <venkatesh.pallipadi@intel.com> Date: Wed Dec 14 15:05:00 2005 -0500 P-state software coordination for ACPI core http://bugzilla.kernel.org/show_bug.cgi?id=5737 Many non-ACPI systems are filling this field by mistake, which makes its usage confusing. Lets clean it. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Acked-by: Santosh Shilimkar <santosh.shilimkar@ti.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
