Subject[PATCH 33/46] usb: turn dev_warn+WARN_ON combos into dev_WARN
Date
From: Arjan van de Ven <arjan@linux.intel.com>

dev_WARN is both compacter and gives better debug information
than just a WARN_ON, since people and tools will copy the device
information message together with the WARN_ON in bug reports.
