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 drivers/staging/comedi/drivers/ni_routes.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) Cc: Spencer Olson <olsonse@umich.edu>
