Bug#570532: linux-source-2.6.26: patch required for yealink.c

[shizuma@vif.com]

yealink uses two URBs that submit each other. This arrangement cannot  
be reliably killed with usb_kill_urb() alone, as there's a window  
during which the wrong URB may be killed. The fix is to introduce a  
flag.

Skype is unreliable whenever the device is connected.  The system
will eventually freeze completely.  No magic key; resetting the
computer is not enough to get it rebooted.  One have to power it
down.
