From 7b1df1985c7a4e6d5fcab0ed71a2cd1d4ad3be41 Mon Sep 17 00:00:00 2001 From: "George G. Davis" Date: Sat, 29 Jul 2006 08:29:27 +0100 Subject: [PATCH] [ARM] 3737/1: Export ARM copy/clear_user_page symbols Patch from George G. Davis As reported by various folks on the ARM Linux kernel mailing list, the video-buf.ko driver has undefined references on all ARM machines which use it as observed during `make modules`: Warning: "v4wb_clear_user_page" [drivers/media/video/video-buf.ko] undefined! Similar warnings exist for all ARM machines which use this driver. So this change adds the missing EXPORT_SYMBOLs to allow using this driver as a module. Signed-off-by: George G.
