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?
Thanks,
Rick
