From fd238232cd0ff4840ae6946bb338502154096d88 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sun, 5 Mar 2006 10:45:09 +0100 Subject: [PATCH] pcmcia: embed dev_link_t into struct pcmcia_device Embed dev_link_t into struct pcmcia_device(), as they basically address the same entity. The actual contents of dev_link_t will be cleaned up step by step. This patch includes a bugfix from and signed-off-by Andrew Morton.
