[PATCH] misc: mei: set IRQF_ONESHOT for MSI request_threaded_irq() in mei_pci_resume()

[Roland Dreier]

From: Roland Dreier <roland@xxxxxxxxxxxxxxx>

When the default quick IRQ handler is used then IRQF_ONESHOT must be set,
or else the request fails and following error is logged on resume:

    genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq ...

This is the same fix that commit aa189ecdc0c7 ("misc: mei: set
IRQF_ONESHOT for msi request_threaded_irq") did in the probe function.

Can you try this?  It looks to be needed.

Thomas/Greg, I think this should get into 3.5 if possible.
