staging: vchiq: convert compat bulk transfer

Browse source

Split out the ioctl implementation for VCHIQ_IOC_QUEUE_BULK_TRANSMIT
into a separate function so it can be shared with the compat
implementation.

Here, the input data is converted separately in the compat
handler, while the output data is passed as a __user pointer
to thec vchiq_queue_bulk_transfer->mode word that is
compatible.
