This is a note to let you know that I've just added the patch titled
mei: pci_resume: set IRQF_ONESHOT for msi request_threaded_irq
to my char-misc git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git
in the char-misc-linus branch.
The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)
The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.
If you have any questions about this process, please let me know.

Subject: mei: pci_resume: set IRQF_ONESHOT for msi request_threaded_irq
when the default irq quick handler is used then IRQF_ONESHOT must be set
otherwise the request fails and following error is displayed:
mei 0000:00:16.0: irq 48 for MSI/MSI-X
genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 48
mei 0000:00:16.0: request_threaded_irq failed: irq = 48.
dpm_run_callback(): pci_pm_resume+0x0/0x140 returns -22
PM: Device 0000:00:16.0 failed to resume async: error -22
