From f6fbe01ac976f3ec618cd5fb71ad9ce2cfa7ab2b Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 20 Jan 2006 15:10:23 +0100 Subject: [PATCH] [PATCH] pcmcia: remove unused p_dev->state flags Remove the unused DEV_RELEASE_PENDING flag, and move the DEV_SUSPEND flag into the p_dev structure, and make use of it at the core level.
