Every µcode-updater must open the cpucontrol devfs node RDWR, open a firmware file, validate the FW file has a positive length, mmap it, etc. De-duplicate that identical logic between every individual platform. Also, constify references to the readonly-mapped firmware files while here. Sponsored by: Dell EMC Isilon
