Hi Andy,
two comment on your ãatch to add MSI support to the above driver.
First pci_alloc_irq_vectors gained a mandatory flags argument, so
for MSI suport you now need to pass PCI_IRQ_MSI in flags for the
code to work.
Second please make sure to always pair pci_alloc_irq_vectors
with pci_free_irq_vectors on the remove path.
Thanks,
Christoph
