The symbol hwa742_update_window_async() is exported, but there is no prototype defined for it. That's why gcc complains: drivers-video-fbdev-omap-hwa742.c:warning:no-previous-prototype-for-hwa742_update_window_async Add the prototype, but I wonder if we couldn't drop exporting the symbol instead. Since omapfb_update_window_async() is exported the same way, are there any users outside of the tree? Signed-off-by: Helge Deller <deller@gmx.de>
