Subject: Device loses its IRQ number on driver unload?
Date: Mon, 9 Mar 2015 11:04:01 +0100	[thread overview]
Message-ID: <54FD7011.8090108@vmware.com> (raw)

Hi,

I'm not sure this started with 4.0 but when I rmmod the device driver
like so
rmmod vmwgfx

The device loses its IRQ line as shown in lscpi:
   Flags: bus master, medium devsel, latency 64 <irq missing here>

and a subsequent modprobe will fail since pdev->irq is 0.

Is anyone else seeing this with other drivers?

Thanks,
Thomas
