Subject: USB: Eliminate urb->status usage!
To: Greg KH <[email protected]>
Cc: David Brownell <[email protected]>, Olav Kongas <[email protected]>, Yoshihiro Shimoda <[email protected]>, Tony Olech <[email protected]>, USB development list <[email protected]>
Message-ID: <[email protected]>
This patch (as979) removes the last vestiges of urb->status from the
host controller drivers and the root-hub emulator. Now the field
doesn't get set until just before the URB's completion routine is
called.
