From 98e4c28b7ec390c2dad6a4c69d69629c0f7e8b10 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 14 Nov 2005 21:21:18 +0100 Subject: [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.
