Let met take a look.

Yes those look like good cleanups.  I had tried to preserve the original
logic in devpts_ptmx_path from devpts_acquire to make it easier to
see if I had goofed.   But that out and out failed so cleanups
so the code is easier to read look like a very good thing.

Actually the NULL initialization is a hold over from the original
version of that function.  But I agree without it gcc could have
caught my use of the wrong variable, so removing it looks like a good
idea.

Thanks.  I will respin and retest and see where things are at.
