From a0aa7d0639277f375989071fb52a7ce78beeef97 Mon Sep 17 00:00:00 2001 From: Adrian Bunk Date: Mon, 9 Jan 2006 20:54:04 -0800 Subject: [PATCH] [PATCH] drivers/video/: possible cleanups This patch contains the possible cleanups including the following: - every file should #include the headers containing the prototypes for it's global functions - make needlessly global functions static - kyro/STG4000Interface.h: #include video/kyro.h and linux/pci.h instead of a manual "struct pci_dev" - i810_main.{c,h}: prototypes for static functions belong to the C file Signed-off-by: Adrian Bunk Acked-by: "Antonino A.
