[PATCH] fbdev: kyrofb: Driver cleanups
- remove unneeded casts - use framebuffer_alloc/framebuffer_release to allocate/free memory - the pseudo_palette is always u32 regardless of bpp if using generic drawing functions Signed-off-by: Antonino Daplas <adaplas@pol.net> Acked-by: Paul Mundt <lethal@linux-sh.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
