Subject: [PATCH] pcmcia: match for fake CIS
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=ea7b38825bba66a81745a706da70a1c81adc95bd;p=linux-beck.git

[PATCH] pcmcia: match for fake CIS

Add another match flag for devices needing a CIS override.  The driver will
only probe/attach if the CIS has been replaced before.
