Re: [PATCH] net: marvell: mvmdio: Handle errors from optional IRQ lookup

platform_get_irq_optional() returns a positive IRQ number on success or
a negative error code on failure. For an optional IRQ, -ENXIO indicates
that no optional IRQ is available. Other errors should be propagated so
that the caller can handle them appropriately.

The existing code propagates -EPROBE_DEFER, but ignores other negative
errors. Propagate negative errors other than -ENXIO.

Found by manual code inspection.

## Form letter - net-next-closed

We have already submitted our pull request with net-next material for v7.3,
and therefore net-next is closed for new drivers, features, code refactoring
and optimizations. We are currently accepting bug fixes only.

Please repost when net-next reopens after Aug 31st.

RFC patches sent for review only are obviously welcome at any time.
