If you select an option, you have to ensure that the dependencies of all 
options you are select'ing are fulfilled.

This patch fixes the following compile error:

<--  snip  -->

...
  LD      .tmp_vmlinux1
fs/built-in.o: In function `debugfs_init':
inode.c:(.init.text+0x3621): undefined reference to `kernel_subsys'
make[1]: *** [.tmp_vmlinux1] Error 1

<--  snip  -->

I've also removed the superfluous "default n".
