driver core: class: make class_for_each_device() options const
class_for_each_device() does not modify the struct class or the struct device passed into it, so mark them as const * to enforce that. Cc: "Rafael J. Wysocki" <rafael@kernel.org> Link: https://lore.kernel.org/r/20230313181843.1207845-6-gregkh@linuxfoundation.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
