[PATCH] usb: dwc3: be more verbose on ERRATIC_ERROR interrupt

From: David Cohen
Date: Tue Oct 14 2014 - 16:14:35 EST


ERRATIC_ERROR interrupt is an event that needs more attention from
developers than currently implemented, since this indicates a serious
stability issue. The only way to get warned about it is by selecting the
maximum driver's verbosity.

This patch increases a bit the error's verbosity.
