Loic Poulain b0fc0167f2 bus: mhi: core: Allow shared IRQ for event rings ... There is no requirement for using a dedicated IRQ per event ring. Some systems does not support multiple MSI vectors (e.g. intel without CONFIG_IRQ_REMAP), In that case the MHI controller can configure all the event rings to use the same interrupt (as fallback). Allow this by removing the nr_irqs = ev_ring test and add extra check in the irq_setup function.
