Here's the other patch. I also added cf8305 support (if_cs.c patched this way works for it too).
From 4c7fcf79de8ba900c4a9a56e68c9da89491dff27 Mon Sep 17 00:00:00 2001 From: Marek Vasut <marek.vasut@xxxxxxxxx> Date: Mon, 23 Mar 2009 16:50:30 +0100 Subject: [PATCH 2/2] Add support for CF8381 and CF8305 WiFi card. Two detection functions were added for identifying CF8381 and CF8305. Also, CF8305 uses only one-stage firmware, so handle this as well.
