firewire: ohci: wait for local CSR lock access to finish
Add a loop to wait for the controller to finish a locally-initiated CSR lock operation. Google shows some occurrences of the "swap not done yet" message which might indicate that some OHCI controllers are not fast enough to do the lock/swap in the time needed for one PCI access. This also correctly handles the case where the lock operation did not finish, instead of silently returning an uninitialized value. Signed-off-by: Clemens Ladisch <> Signed-off-by: Stefan Richter <>
