[PULL 53/71] memory: Have memory_region_init_rom_device() handler return a boolean

[Philippe Mathieu-Daudé]

Following the example documented since commit e3fe3988d7 ("error:
Document Error API usage rules"), have memory_region_init_rom_device
return a boolean indicating whether an error is set or not.
