[ofa-general] CM sysfs-related oops on device driver reload

[Sean Hefty]

The changes themselves look fine to me, but I'm not sure that I fully understand
the issue.

Was this function the cause of the problem?  Was the cm port object freed while
references were still on one of the cm counter objects?
