Subject: [PATCH 0/1] iommu/riscv: Support sharing irq lines between iommu queues

This is an additional patch for Tomasz Jeznach's riscv iommu driver
patch series[1].

It seems that when the number of wired irq lines is less than the number
of iommu queues, iommu platform driver does not assign virtual irqs for
iommu queues whose id exceeds the total number of irq lines.

If it is a problem worth fixing, please feel free to merge this patch
into existing commits. And please ignore this patch if we don't think
it is a problem.
