commit 20dcff436e9fcd2e106b0ccc48a52206bc176d70 upstream.
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.
