pcmcia: move unbind/rebind into dev_pm_ops.complete
Move the device rebind procedures for cardbus devices from the pm.resume into the pm.complete callback. The reason for moving the code is: "[...] The PM code needs to send suspend and resume messages to every device in the right order, and it can't do that if new devices are being added at the same time. [...]" However the situation really isn't quite that rigid. In particular, adding new children during a resume callback shouldn't cause much of problem because the children don't need to be resumed anyway (since they were never suspended). On the other hand, if you do it you will get a dev_warn() from the PM core, something like 'parent should not be sleeping'. Still, it is considered bad form and should be avoided if possible."
