Anyway, thank you for you time reviewing it. :)

What do you mean? I thought returning the error code was enough.

They do 8)

#define PRINTK_PREFIX PRINTK_INFO NAME ": "

printk(PRINTK_PREFIX "Init... ");

Then, if a error appears: printk("ERROR - kmalloc\n");

Final string: "<i>cfag12864b: Init... ERROR - kmalloc"

The only bad point: If some other printk is called from other module
between. Should I change it?
