patch "usb: cdns3: Fix issue with using incorrect PCI device function" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: cdns3: Fix issue with using incorrect PCI device function

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-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: usb: cdns3: Fix issue with using incorrect PCI device function

PCI based platform can have more than two PCI functions. USBSS PCI Glue driver during initialization should consider only DRD/HOST/DEVICE PCI functions and all other should be ignored. This patch adds additional condition which causes that only DRD and HOST/DEVICE function will be accepted.
