Where the hell is it creating any char device nodes? Show me.
And note that device_create() is not creating *any* device nodes,
char or block. It creates a directory in some place in sysfs,
associated with struct device (which has arseloads of uses unrelated
to block *or* char devices) and, if dev_t argument is non-zero,
dumps its value into one of the attributes.
These days it might also dump a symlink into /sys/dev/*.
Which part of the above constitutes a creation of char device node?
