I create a static mut Mutex<&str> (or similar) to contain the pr_fmt
string. I cannot init the mutex in a const fn, and so I cannot create an
static mut value which already contains a mutex. So I have to call an
init_printk functions which creates this mutex. That's all what I'm doing.
Will try to get something working the following days, and then send a
patch. Mayebe easier to decide then.
