[PATCH] pcmcia: default suspend and resume handling
In all but one case, the suspend and resume functions of PCMCIA drivers contain mostly of calls to pcmcia_release_configuration() and pcmcia_request_configuration(). Therefore, move this code out of the drivers and into the core. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
