[PATCH 5.12 313/363] usb: dwc3: imx8mp: fix error return code in dwc3_imx8mp_probe()

[Greg Kroah-Hartman]

From: Zhen Lei <thunder.leizhen@xxxxxxxxxx>

commit 0b2b149e918f6dddb4ea53615551bf7bc131f875 upstream.

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

Fixes: 6dd2565989b4 ("usb: dwc3: add imx8mp dwc3 glue layer driver")
