patch "usb: dwc3: core: Fix tx/rx threshold settings" added to usb-linus

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

usb: dwc3: core: Fix tx/rx threshold settings

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: dwc3: core: Fix tx/rx threshold settings

The current driver logic checks against 0 to determine whether the periodic tx/rx threshold settings are set, but we may get bogus values from uninitialized variables if no device property is set. Properly default these variables to 0.
