-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.
