This enhances the pca2xx driver's interrupt handler with support for edge-triggered interrupts and makes use of that for PCI-hosted variants, like the Intel Quark SoC.
Changes in v3: - removed already applied patch "Factor out handle_bad_msg" - avoid inner looping by making the hardware retrigger on "forgotten" IRQ sources - added acked/reviewed tags
Changes in v2: - factored out handle_bad_msg (Andy) - reordered code in patch 3, avoiding unneeded pci_free_irq_vectors (Andy)
