+Subject: [PATCH] staging: mmal-vchiq: Fix client_component for 64 bit
+ kernel
+
+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.
