[2.6.22.2 review 40/84] pcmcia: give socket time to power down

From: Greg KH
Date: Tue Aug 07 2007 - 17:07:22 EST



From: Daniel Ritz <daniel.ritz-ml@xxxxxxxxxxxxxx>

Give sockets up to 100ms of additional time to power down. otherwise we
might generate false warnings with KERN_ERR priority (like in bug #8262).
