Shaun Ruffell 0ecf2c67c8 dahdi_dynamic_loc: Change and check the dyn->pvt pointer under lock. ... Fixes a crash on unload if the sync_tick callback was running at the same time the dynamic local span was destroyed. It was possible for dahdi_dynamic_local_transmit to dereference a pointer that may have already been freed.
