[PATCH] pcmcia: new suspend core
Move the suspend and resume methods out of the event handler, and into special functions. Also use these functions for pre- and post-reset, as almost all drivers already do, and the remaining ones can easily be converted. Bugfix to include/pcmcia/ds.c Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
