Actually I think we should delete the duplicate code now while merging this. So I queued this up for 2.6.22:
commit f19c8d7cbe3153d68f0a559afd02f66655310238 Author: Joachim Fenkes <fenkes@de.ibm.com> Date: Mon Apr 23 18:20:27 2007 +0200
IB: Set class_dev->dev in core for nice device symlink
All RDMA drivers except ehca set class_dev->dev to their dma_device value (ehca leaves this unset). dma_device is the only value that makes any sense, so move this assignment to core/sysfs.c. This reduce the duplicated code in the rest of the drivers and gives ehca a nice /sys/class/infiniband/ehcaX/device symlink.
