From 79b66128f13f5c22dea03a2197495c4b96ab31f5 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Sun, 29 May 2022 08:35:52 +0200 Subject: [PATCH] video: fbdev: omap: Add prototype for hwa742_update_window_async() 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?
