[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 <deller@gmx.de> Acked-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
