Subject: [PATCH 07/13] platform/raspberrypi: vchiq-mmal: Free the event
 context for control ports

From: Dave Stevenson <dave.stevenson@...pberrypi.org>

vchiq_mmal_component_init calls init_event_context for the
control port, but vchiq_mmal_component_finalise didn't free
it, causing a memory leak..

Add the free call.
