[RESEND AGAIN][PATCH] pcmcia: move unbind/rebind into dev_pm_ops.complete

[Christian Lamparter]

The idea of moving rebind procedure into pm.complete
was taken from the usb-subsystem, which has similar
problems with reattaching devices during/after
resume.

To Greg:

I have submitted this patch back in March and again in May.
As far as I can tell it was neither rejected nor was it
accepted into linux-pcmcia.git since. So I'm asking you,
if you could take the patch instead... please.
 
Regards,
	Christian

PS: I'm not on the pcmcia/kernel list, so please keep the
'CC'.
