s3fb: implement fb_get_caps
Implement fb_get_caps(). This will allow the driver to tell upper layer that it can only support 256 8x16 bitmaps when in tileblitting mode (var->bits_per_pixel == 0); Signed-off-by: Antonino Daplas <adaplas@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
