ChangeSet 1.1832.55.21, 2004/09/03 13:33:55+02:00, [EMAIL PROTECTED]
[PATCH] USB: Nag message for usb_kill_urb
This patch is only for nuisance value. It puts a nag message in the
system log every time usb_unlink_urb() is called for synchronous
unlinking. My hope is this will speed the process of converting drivers
to use usb_kill_urb().
Don't apply this if it generates too much noise, but otherwise go ahead.
A little prodding never hurt anyone.
