Can you please take my cleanups to devpts_ptmx_path() too?

Those 'goto err' statements are disgusting, when a plain 'return
-ERRNO' works cleaner.

And that "struct file *filp = NULL;" is bogus - you added the NULL
initialization because you mis-used "filp" early, and with that fixed
it's just garbage.

Other than that, it looks fine to me.
