Hi,
With current way of device reporting in RapidIO subsystem you will need
to have at least one SRIO device (switch or EP) attached to your mport
to be able to find a reference to that mport device object. Like in the code
fragment below:
static int rioport_init_module(void)
{
int ret,

You forgot to include the evidence that performance has improved, as well
as an explanation why it's okay to use spin_lock_bh, and why it's faster.
