From 43821242078aeced1d576b4b54d7b4a9bd76ec05 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 3 May 2010 15:10:09 +0200 Subject: [PATCH] pcmcia: order userspace suspend and resume requests Assert that userspace suspend and resume requests appearing (almost) immediately are executed in the following order: suspend, resume. This should result in "pccardctl reset" behaving the same as before.
