From: Adrian Bunk Date: Tue, 10 Jan 2006 04:54:04 +0000 (-0800) Subject: [PATCH] drivers/video/: possible cleanups X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a0aa7d0639277f375989071fb52a7ce78beeef97;p=linux-beck.git [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.
