See commits 422f07001d6638fdde28f1909cc9162bc7f571d3..104c4fe25dc9bde823ba4591e910a77071b98ab5
Especially the first one.

Probably the best course of action is to remove proc_info code from
these drivers because the interface was deprecated for a long time.

The amount of code once removed from staging prevented me from doing
any work on them.

Looking at staging ->read_proc users this is going to be a problem for
its removal. :-(
