ACPI: EC: Return bool from acpi_ec_dispatch_gpe()
On some systems, if suspend-to-idle is used, the EC may signal system wakeup events (power button events, for example) as well as events that should not cause the system to resume and acpi_ec_dispatch_gpe() needs to be called to determine whether or not the system should resume then. In particular, if acpi_ec_dispatch_gpe() doesn't detect any EC events at all, the system should remain suspended, so it is useful to know when that is the case. For this reason, make acpi_ec_dispatch_gpe() return a bool value indicating whether or not any EC events have been detected by it. Signed-off-by: Rafael J.
