This is a note to let you know that I've just added the patch titled
usb: dwc3: core: add phy cleanup for probe error handling
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-testing 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 be merged to the usb-next branch sometime soon, after it passes testing, and the merge window is open.
If you have any questions about this process, please let me know.

Add the phy cleanup if dwc3 mode init fail, which is the missing part of de-init for dwc3 core init.
