Yeah, this is a dumb bug. I fixed that.

Adding:

commit 138027e74e9f602e3bb91112dd38840c7a5007e4
Author:     Christian Brauner <brauner@kernel.org>

    devpts: preserve original file opening pattern

    LTP seems to have assertions about what errnos are surfaced in what
    order. I think that's often misguided but we can accomodate this here
    and preserve the original order.

    This also makes sure to unconditionally release the reference on the
    mount that we've taken after we opened the file.

    Fixes: https://lore.kernel.org/37ac7af5-584f-4768-a462-4d1071c43eaf@sirena.org.uk
    Fixes: b945a44e919a ("tty: convert ptm_open_peer() to FD_ADD()")
