This is a note to let you know that I've just added the patch titled
usb: dwc3: fix the glue drivers using the nop phy
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-next 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 also be merged in the next major kernel release
during the merge window.
If you have any questions about this process, please let me know.

Subject: usb: dwc3: fix the glue drivers using the nop phy
The reset_gpio member of the usb_phy_gen_xceiv_platform_data
structure needs the have negative value or phy-generic's
probe will fail unless DT is used. 0 is a valid gpio number.
This fixes an issue where phy-generic fails to probe with
message: "usb_phy_gen_xceiv.0: Error requesting RESET GPIO 0".
