USB: Move private hub declarations out of public header file
Browse files Browse the repository at this point in the history
This patch (as809b) moves the declaration of the hub driver's private
data structure from hub.h into the hub.c source file.  Lots of other
files import hub.h; they have no need to know about the details of the
hub driver's private data.
