From adf6b206546414fd006098d027e81f2b576ea2aa Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Fri, 8 Dec 2006 02:40:27 -0800 Subject: [PATCH] fbcmap.c: mark structs const or __read_mostly - Mark the default colormaps read-only, as nobody should be allowed to modify them - Additionally mark color values as __read_mostly since they will only be modified (very seldom) by fb_invert_cmaps() - Add named C99-initializers in fb_cmap structs and use the ARRAY_SIZE() macro Signed-off-by: Helge Deller Acked-by: James Simmons Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/fb.h | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'include') diff --git a/include/linux/fb.h b/include/linux/fb.h index fa23e0671bb3..6fe56aaa6685 100644 --- a/include/linux/fb.h +++ b/include/linux/fb.h @@ -970,11 +970,11 @@ extern struct fb_videomode *fb_find_best_display(struct fb_monspecs *specs, /* drivers/video/fbcmap.c */ extern int fb_alloc_cmap(struct fb_cmap *cmap, int len, int transp); extern void fb_dealloc_cmap(struct fb_cmap *cmap); -extern int fb_copy_cmap(struct fb_cmap *from, struct fb_cmap *to); -extern int fb_cmap_to_user(struct fb_cmap *from, struct fb_cmap_user *to); +extern int fb_copy_cmap(const struct fb_cmap *from, struct fb_cmap *to); +extern int fb_cmap_to_user(const struct fb_cmap *from, struct fb_cmap_user *to); extern int fb_set_cmap(struct fb_cmap *cmap, struct fb_info *fb_info); extern int fb_set_user_cmap(struct fb_cmap_user *cmap, struct fb_info *fb_info); -extern struct fb_cmap *fb_default_cmap(int len); +extern const struct fb_cmap *fb_default_cmap(int len); extern void fb_invert_cmaps(void); struct fb_videomode { -- cgit v1.2.3
