ACPI: EC: Avoid queuing unnecessary work in acpi_ec_submit_event()
Notice that it is not necessary to queue up the event work again if the while () loop in acpi_ec_event_handler() is still running which is the case if nr_pending_queries is greater than 0 at the beginning of acpi_ec_submit_event() and modify the code to avoid doing that. While at it, rename nr_pending_queries in struct acpi_ec to events_to_process which actually matches the role of that field and change its data type to unsigned int which is sufficient. No expected functional impact. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
