Fix some regressions resulting from the routing functionality implemented for the National Instruments comedi drivers in kernel 4.20 when board-specific routing information is absent.
Patch 1 fixes a null pointer dereference, but the set-up of asynchronous commands that use external triggers on boards with missing board-specific routing information will now fail gracefully with an error.
Patch 2 allows routing values for the device family to be filled in even if the board-specific routing information is missing, which should allow asynchronous commands that use external triggers to be used on these boards.
1) staging: comedi: ni_routes: fix null dereference in ni_find_route_source() 2) staging: comedi: ni_routes: allow partial routing information
