Hi, I'm trying to write a simple driver using some registers of my hardware. Is a call to request_mem_region() advisory ("recommended") or compulsory before I ioremap the memory? In other words, if I don't use request_mem_region() before I start using the memory; is my driver BOUND to fail, or it MAY fail?
