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. |
