Subject[PATCH] 8250_pci: improve code comments and Kconfig help
Date
From: Stefan Seyfried <seife+kernel@b1-systems.com>

The recent regression about NetMos 9835 Multi-I/O boards indicates
that comment pointing to the parport_serial driver could be helpful.

This builds standard PCI serial support. You may be able to
disable this feature if you only need legacy serial support.
Saves about 9K.
