Subject: [SERIAL] Collapse the SIIG quirk entries
X-Git-Tag: v2.6.14-rc1~1053^2~4
X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=67d74b870725448e0108984eec551609771e6b73;p=linux-2.6

[SERIAL] Collapse the SIIG quirk entries

Collapse all the SIIG quirk entries into one.  SIIG10x cards all
have PCI device IDs of 0x10xx, SIIG20x cards all have PCI device
IDs of 0x20xx.
