David Brownell 29c8f6a727 USB: ohci - record data toggle after unlink ... This patch fixes a problem with OHCI where canceling bulk or interrupt URBs may lose track of the right data toggle. This seems to be a longstanding bug, possibly dating back to the Linux 2.4 kernel, which stayed hidden because (a) about half the time the data toggle bit was correct; (b) canceling such URBs is unusual; and (c) the few drivers which cancel these URBs either [1] do it only as part of shutting down, or [2] have fault recovery logic, which recovers. For those transfer types, the toggle is normally written back into the ED when each TD is retired. But canceling bypasses the mechanism used to retire TDs ... so on average, half the time the toggle bit will be invalid after cancelation. The fix is simple: the toggle state of any canceled TDs are propagated back to the ED in the finish_unlinks function. (Issue found by leonidv11@gmail.com ...)
