[PATCH 4.17 14/46] serial: 8250_pci: Remove stalled entries in blacklist

[Greg Kroah-Hartman]

4.17-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Andy Shevchenko <andriy.shevchenko@xxxxxxxxxxxxxxx>

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.
