infiniband: rename "device" to "ib_device" in cm_device
Browse files Browse the repository at this point in the history 
This pointer really is a struct ib_device, not a struct device, so name
it properly to help prevent confusion.

This makes the followon patch in this series much smaller and easier to
understand as well.
