From b463581154f3f3eecda27cae60df813fefcd84d3 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Mon, 14 Nov 2005 21:25:35 +0100 Subject: [PATCH] pcmcia: remove dev_list from drivers The linked list of devices managed by each PCMCIA driver is, in very most cases, unused. Therefore, remove it from many drivers.
