Remove unnecessary empty return statement at the end of a void
function in the following:
- drivers/pci/hotplug/cpci_hotplug_core.c: cleanup_slots()
- drivers/pci/hotplug/cpqphp_core.c: pci_print_IRQ_route()
- drivers/pci/hotplug/cpqphp_ctrl.c: cpqhp_pushbutton_thread()
- drivers/pci/hotplug/cpqphp_ctrl.c: interrupt_event_handler()
- drivers/pci/hotplug/cpqphp_nvram.h: compaq_nvram_init()
- drivers/pci/hotplug/rpadlpar_core.c: rpadlpar_io_init()
- drivers/pci/hotplug/rpaphp_core.c: cleanup_slots()

Applied to pci/trivial for v5.4, thanks!
I squashed the mediatek patch into this since they're both trivial.
