This seems to be a trap that is easily hit, so I added some clarifications to the docbook comments for the device registration functions. Looking further at the driver core code, I found that device_create_vargs() contains the same bug. The patches are on top of the driver core quilt. [Patch 1/2] Driver core: Clarify device cleanup. [Patch 2/2] Driver core: Fix cleanup in device_create_vargs().
