Pktcdvd creates char _and_ block device nodes at the same time, while
the char nodes are not allocated, but created and conflict in
/sys/dev/ with properly allocated ones from other subsystems. Your
patch just papers over this bug.

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?

Wait a minute... Are you saying that something in userland ends up
seeing that sucker, noticing .../dev and proceeding to do mknod?
