Yes, that appears to work for 'void *' -> __iomem, but not the other way around:

+       return devm_regmap_init(dev, NULL, (void *)base, &regmap_cfg);

sparse generates:
drivers/staging/fieldbus/anybuss/arcx-anybus.c:156:16: warning: cast
removes address space of expression

Would it be a ok solution to use __force in this instance only?
