This is a note to let you know that I've just added the patch titled
usb: host: xhci-tegra: otg usb2/usb3 port init
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.

tegra_xusb_init_usb_phy() should initialize "otg_usb2_port" and "otg_usb3_port" with -EINVAL because "0" is a valid value represents usb2 port 0 or usb3 port 0.
