[PATCH v3 0/2] serial: 8250_pci patches to address issues with pericom_do_set_divisor()

[Andy Shevchenko]

A series patches to address three issues one customer managed to hit
all at once.

1) Fourth port not being setup correctly on some Pericom chips. Fix
the entries in pci_serial_quirks array.

2) Rewrite pericom_do_set_divisor() to always calc divisor and to use
the uartclk instead of a hard coded value. Always calculate divisor
without passing control to serial8250_do_set_divisor().

Jay, can you test this again, please?

Changelog v3:
- fix possible division by 0 in patch 2 (Jay)

Changelog v2:
- dropped no-fixes patch, left only fixes here
- amended refactoring of the ->set_divisor()
- fixed Fixes tags
