Char: cyclades, create cy_init_Ze
Move Ze init code into new cy_init_Ze, because we will need it in another place and it will make the code totally unreadable. Signed-off-by: Jiri Slaby <jirislaby@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
