commit e989a73e upstream.

Fix an oops during device initialization by correctly setting size_of_priv
instead of leaving it 0.
The regression was introduced by 8abe4a0a ("[media] dib7000:
export just one symbol") and only fixed for one type of dib0700 based
devices in 9e334c75 ("[media] Fix regression in some dib0700
based devices").
