This is not a good way to do it. See e.g. fs/pipe.c#read_fifo_fops
for an easier approach:

struct file_operations read_fifo_fops = {
        llseek:         no_llseek,
        read:           pipe_read,
        write:          bad_pipe_w,
        poll:           fifo_poll,
        ioctl:          pipe_ioctl,
        open:           pipe_read_open,
        release:        pipe_read_release,
};
