3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: Sarah Sharp <sarah.a.sh...@linux.intel.com>
commit 2a9227a5eeaeb3f91e3a72ceea4fa59016ca5d20 upstream.
Getting a short packet or a babble error is usually a recoverable error,
so stop scaring users with warnings in dmesg when xHCI debugging is turned
off.
