Subject: [PATCH] ITE_887x parport and serial driver
Date: Tue, 27 May 2003 15:06:04 +0800	[thread overview]
Message-ID: <DC62C613C2F7274C9D361EA476413476392C25@itemail1.internal.ite.com.tw> (raw)

887x  driver patch, the patch modity parport_pc.c and parport_serial.c
I remove the driver from parport_pc.c then combine serial port to parport_serial.c. 
887x is a parport + serial ports pci card , and the type is from 8871 to 8875. 
All the vendor: device id are 1283:8872 , 
(8871 ~ 8875 use the same vendor:device id  1283:8872)
