[SBUSFB]: implement ->compat_ioctl
This patch adds a new function, sbusfb_compat_ioctl() to drivers/video/sbuslib.c and uses it as compat_ioctl in all sbus fb drivers This remove the last per-arch compat ioctl bits in arch/sparc64/kernel/ioctl32.c so it would be nice if people could test if this actually copiles and works and if yes apply it :) Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: David S. Miller <davem@davemloft.net>
