+Date: Wed, 2 Jul 2008 22:36:46 +0100
+Subject: [PATCH] introduce-samsung-camera-unit-driver.patch
+
+This is the kernel side of an old (2004) samsung camera driver for 2440
+It doesn't compile on modern kernel yet, this patch introduces it into the
+kernel tree without gross mods, so it is broken code we can start to work on
