Re: [PATCH v5 05/17] PCI: dwc: Export dw_handle_msi_irq()

[sashiko-bot@kernel.org]

> Not every platform brings the iMSI-RX interrupt out as a dedicated
> line. On spear13xx and keembay it is a status bit in the SoC wrapper's
> interrupt register that the glue driver has to check and clear, and on
> dra7xx it shares the line with other sources the glue driver has to
> demultiplex. These drivers set msi_irq[0] to -ENODEV so the core does
> not install its chained handler, and service the MSIs from a handler of
> their own. spear13xx and keembay call dw_handle_msi_irq() for that.
> Both are built-in, so the function was never exported. dra7xx can be a
> module and has an MSI loop of its own.
> 
> Export the function so that modular glue drivers can use it as well.
> The pcie-rcar-gen4 driver, where both situations apply, is the first user.
