patch "serial: 8250_pci: Remove stalled entries in blacklist" added to tty-linus

[gregkh]

This is a note to let you know that I've just added the patch titled

    serial: 8250_pci: Remove stalled entries in blacklist

to my tty git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/tty.git
in the tty-linus branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: serial: 8250_pci: Remove stalled entries in blacklist

After the commit

  7d8905d06405 ("serial: 8250_pci: Enable device after we check black list")

pure serial multi-port cards, such as CH355, got blacklisted and thus
not being enumerated anymore. Previously, it seems, blacklisting them
was on purpose to shut up pciserial_init_one() about record duplication.

So, remove the entries from blacklist in order to get cards enumerated.
