Message-Id: <1413317705-10194-1-git-send-email-david.a.cohen@linux.intel.com> Date: Tue, 14 Oct 2014 13:15:05 -0700 From: David Cohen <david.a.cohen@...ux.intel.com> To: balbi@...com, gregkh@...uxfoundation.org Cc: linux-usb@...r.kernel.org, linux-kernel@...r.kernel.org, David Cohen <david.a.cohen@...ux.intel.com> Subject: [PATCH] usb: dwc3: be more verbose on ERRATIC_ERROR interrupt 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.
