staging: mmal-vchiq: Fix client_component for 64 bit kernel
[ Upstream commit 22e64b486adc4785542f8002c3af4c895490f841 ]
The MMAL client_component field is used with the event
mechanism to allow the client to identify the component for
which the event is generated.
The field is only 32bits in size, therefore we can't use a
pointer to the component in a 64 bit kernel.
Component handles are already held in an array per VCHI
instance, so use the array index as the client_component handle
to avoid having to create a new IDR for this purpose.
