patch "usb: missing parentheses in USE_NEW_SCHEME" added to usb-linus

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

usb: missing parentheses in USE_NEW_SCHEME

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: missing parentheses in USE_NEW_SCHEME

According to bd0e6c9614b9 ("usb: hub: try old enumeration scheme first for high speed devices") the kernel will try the old enumeration scheme first for high speed devices. This can happen when a high speed device is plugged in.

But due to missing parentheses in the USE_NEW_SCHEME define, this logic can get messed up and the incorrect result happens.
