From 4d8582967a124a215baac71664035b0d6d4a346f Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 25 Nov 2008 22:26:38 +0100 Subject: uvcvideo: Prevent compat.h from being included in userspace code. From: Laurent Pinchart When used in userspace code, the uvcvideo.h header shouldn't pull compat.h. Make sure this won't happen by moving the #include to a __KERNEL__ protected section.
