[LinuxCNC/linuxcnc PR#401] fix null pointer dereference for bidirectional pins on smart serial s…

#1 – SebKuzminsky 于 2018-01-21

The pin direction handling in 2.7’s sserial looks the same as master’s before this PR. Does 2.7 have this bug as well? If so that’s where the fix should go, then we’ll merge 2.7 into master to get the fix there too.

@rene-dev reports on IRC that 2.7 doesn’t have this bug.
