From b498ada6d0cf0f9828b0c590f9fa2e84f60f5709 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Sat, 20 Mar 2010 19:43:26 +0100 Subject: pcmcia: dev_node removal (remaining drivers) As a fourth step, remove any remaining usages of dev_node_t from drivers: - ipwireless can be simplified a bit, as we do not need to pass around the (write-only) dev_node_t around. - avma1_cs can be simplified as well, if we only keep the minor number around as "priv" data, not a full-fledged struct.
