+Subject: usb: Remove annoying warning about bogus URB
+
+When ath9k-htc Wi-Fi dongle is used with generic OHCI controller
+infinite stream of warnings appears in debug console like this:
+-------------------------->8----------------------

+
+There're some discussions in mailing lists proposing to disable
+that particular check alltogether and magically all seem to work
+fine with muted warning.
+
+Anyways new thread on that regard could be found here:
+http://lists.infradead.org/pipermail/linux-snps-arc/2016-July/001310.html
+
+Let's see what comes out of that new discussion, hopefully patching
+of generic USB stuff won't be required then.
