[PATCH 3.12 05/27] staging: comedi: adl_pci9111: fix incorrect irq passed to request_irq()

From: Greg Kroah-Hartman
Date: Thu Jan 23 2014 - 14:13:04 EST

3.12-stable review patch. If anyone has any objections, please let me know.


From: H Hartley Sweeten <hsweeten@xxxxxxxxxxxxxxxxxxx>

commit 48108fe3daa0d142f9b97178fdb23704ea3a407b upstream.

The dev->irq passed to request_irq() will always be 0 when the auto_attach
function is called. The pcidev->irq should be used instead to get the correct
irq number.
