Dominik Brodowski e2d4096365 [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.
