pcmcia: use pccardd to handle eject, insert, suspend and resume requests
This avoids any sysfs-related deadlock (or lockdep warning), such as reported at http://lkml.org/lkml/2010/1/17/88 . Reported-by: Ming Lei <tom.leiming@gmail.com> Tested-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
