Drivers: hv: vmbus: Teardown clockevent devices on module unload
Newly introduced clockevent devices made it impossible to unload hv_vmbus module as clockevents_config_and_register() takes additional reverence to the module. To make it possible again we do the following: - avoid setting dev->owner for clockevent devices; - implement hv_synic_clockevents_cleanup() doing clockevents_unbind_device(); - call it from vmbus_exit(). In theory hv_synic_clockevents_cleanup() can be merged with hv_synic_cleanup(), however, we call hv_synic_cleanup() from smp_call_function_single() and this doesn't work for clockevents_unbind_device() as it does such call on its own. I opted for a separate function. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: K. Y.
