thermal: cpu cooling: use const parameter while registering
There are predefined cpu_masks that are const data structures. This patch changes the cpu cooling register function so that those const cpu_masks can be used, without compilation warnings. include/linux/cpumask.h * The following particular system cpumasks and operations manage * possible, present, active and online cpus. * * cpu_possible_mask- has bit 'cpu' set iff cpu is populatable * cpu_present_mask - has bit 'cpu' set iff cpu is populated * cpu_online_mask - has bit 'cpu' set iff cpu available to scheduler * cpu_active_mask - has bit 'cpu' set iff cpu available to migration * Signed-off-by: Eduardo Valentin <eduardo.valentin@ti.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
