Makes sense. It would probably require reverting the 640e77466e69 
("staging: mmal-vchiq: Avoid use of bool in structures")

I'll also find other occurances in vchiq-mmal (if any). Also for other 
reviewers, I found the context at:

7967656ffbfa ("coding-style: Clarify the expectations around bool")

Thanks,
