Hi Andrew,
When I remove the call devm_free_irq, I get a segmentation fault on close
in pci_disable_msix. Did I do something else wrong?
Also I'm allocating interrupt resources on interface up, and freeing resources
on interface down. So if there is an up, down, up sequence then the driver
will allocate resources twice. In order for devm to work properly, should I
move all resource allocation into the probe function?
