Thanks for the patch. I extended it a bit further:

Subject: [PATCH] pcmcia: fix yenta dependency on PCCARD_NONSTATIC

With CONFIG_PCMCIA=m and CONFIG_YENTA=y, we get

drivers/built-in.o: In function `yenta_probe':
yenta_socket.c:(.devinit.text+0x1e582): undefined reference to
`pccard_nonstatic_ops'

This is because

select PCCARD_NONSTATIC if PCMCIA

sets PCCARD_NONSTATIC = min(YENTA, PCMCIA). Change it to 'if PCMCIA!=n'
to remove the upper limit.
