resource_setup_done is still needed.
What about this patch?
From: Dominik Brodowski
Date: Wed, 21 Jul 2010 14:43:05 +0200
Subject: [PATCH] pcmcia: remove unused flag, simplify headers
As we only provide one way to set up resources now, we can remove
the resource-setup-related bitfield (except resource_setup_done).
In addition, pcmcia_state only consisted of one entry, so remove
this bitfield as well.
