Revision 70e8b40176c75d3544024e7c934720b11a8a11bf authored by Bjorn Helgaas on 08 September 2016, 21:43:40 UTC, committed by Bjorn Helgaas on 14 September 2016, 19:24:25 UTC
After 1469d17dd341 ("PCI: pciehp: Handle invalid data when reading from
non-existent devices"), we returned IRQ_HANDLED when we failed to read
interrupt status from the bridge.  I think it's better to return IRQ_NONE,
as we do in other cases where there's no interrupt pending.  This will
facilitate refactoring the loop in pcie_isr(): we'll be able to call the
ISR in a loop as long as it returns IRQ_HANDLED.

Return IRQ_NONE if we couldn't read interrupt status.
