This struct is part of the VCHIQ userspace API, which we
don't want to break. So move the struct definition to
vchiq.h, which contains the rest of the userspace API.

Hi Stefan,

Thank you for the patch.

Dies it ? vchiq.h contains lots of kernel API elements. Beside, we have
headers such as vc04_services/interface/vchiq_arm/vchiq_ioctl.h that
contain UAPI elements.

Splitting the UAPI to separate headers is a good idea. Could you address
that task as a whole, and create a
drivers/staging/vc04_services/include/uapi/linux/raspberrypi/vchiq.h
file for the whole UAPI ?
