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.

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.
