[PATCH V4 04/11] ACPI: remove unsupported serial PNP ids from acpi pnp scan handler id lsit

From: Zhang Rui
Date: Mon Mar 17 2014 - 03:52:59 EST

The "serial" pnp driver supports some unknown PNP modems (PNPCXXX/PNPDXXX)
by matching magic strings in the pnp device name or the pnp device card name.

ACPI enumerated PNP device neither supports pnp card, nor supports those magic
strings in its device name, which means this mechamism never works for ACPI
enumerated PNPCXXX/PNPDXXX devices.
So it is safe to remove those two ids from the ACPI pnp scan handler id list.
