Very happy you like it, yes I wasn't sure what was the correct way to
introduce the helper. If you notice in the blkdev.h we have also add_disk()
that is a static inline wrapper for device_add_disk().

Wonder if device_add_disk() should have the same treatement? No idea if
it would cause problem with symbol with external modules, that is why I
used the wrapper.

sure! I will wait the usual 24h to respin this.
