Subject: USB: net2280: Handle STALLs for 0-length control-IN requests
Message-ID: <Pine.LNX.4.44L0.0604141635240.5320-100000@iolanthe.rowland.org>

This patch (as668) fixes a typo in net2280.  The handler for 0-length
control-IN requests should check that the endpoint _isn't_ halted before
sending a 0-length packet.
