But if you still want to have something, what about rather this

       for (i = 0, dev = console_devices[file][0];     \
            i < cd_count[file];                        \
            i++, dev = console_devices[file][i])

?

Or if it's still complains

       for (i = 0, dev = cd_count[file] ? console_devices[file][0] : NULL;     \
            i < cd_count[file];                        \
            i++, dev = console_devices[file][i])

?
