Subject: PCMCIA regression

Hi

The commit a8408c17d0038b76a83affb1b56dc18fa1e7ed86 in Linux 2.6.34-rc6 
broke pcmcia for me. I use 3c574 network card in yenta socket on Armada 
7400 laptop. My distribution is Debian lenny.

Reverting the test for "s->functions" in pccard_validate_cis makes the 
network card work again.

Mikulas
