patch "usb: dwc3: imx8mp: fix error return code in dwc3_imx8mp_probe()" added to usb-linus

[gregkh]

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

    usb: dwc3: imx8mp: fix error return code in dwc3_imx8mp_probe()

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.

Fix to return a negative error code from the error handling case instead
of 0, as done elsewhere in this function.
