[PATCH] chardev: GPIO for SCx200 & PC-8736x: device minor numbers are unsigned ints
Per kernel headers, device minor numbers are unsigned ints. Do the same in this driver. Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
