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----------------------

|
usb 1-1: new full-speed USB device number 2 using ohci-platform

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.
