sh: Don't use create_proc_read_entry()
Don't use create_proc_read_entry() as that is deprecated, but rather use proc_create_data() and seq_file instead. Signed-off-by: David Howells <dhowells@redhat.com> cc: Paul Mundt <lethal@linux-sh.org> cc: linux-sh@vger.kernel.org Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
