From e2d4096365e06b9a3799afbadc28b4519c0b3526 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Thu, 2 Mar 2006 00:09:29 +0100 Subject: [PATCH] pcmcia: use bitfield instead of p_state and state Instead of the two status values struct pcmcia_device->p_state and state, use descriptive bitfields. Most value-checking in drivers was invalid, as the core now only calls the ->remove() (a.k.a. detach) function in case the attachement _and_ configuration was successful.
