[PATCH] pcmcia: permit single-character identifiers

For some time, the core pcmcia drivers seem not to think single
character prod_ids are valid, thus preventing the "cleverly" named

  "D" "Link DWL-650 11Mbps WLAN Card"

Before (as in 2.6.16):
PRODID_1=""
PRODID_2="Link DWL-650 11Mbps WLAN Card"
PRODID_3="Version 01.02"
PRODID_4=""
MANFID=0156,0002
FUNCID=6

After (with the patch)
PRODID_1="D"
PRODID_2="Link DWL-650 11Mbps WLAN Card"
PRODID_3="Version 01.02"
PRODID_4=""
MANFID=0156,0002
FUNCID=6
