    Yes, it could be better, although it is not necessary for now (link
    order is telling who should get called first).

    Yes, link order matters; however, the problem is related to
    cfag12864b_init() being called if ks0108 failed. Indeed, if cfag12864b
    is called before ks0108 is a mistake too, but it isn't happening here.

    I also think the solution looks hacky (I said that I was waiting for a
    better solution), and also I think it should be checked by the kernel
    at boot like modprobe does; but I don't know any other solution. Any
