From 1bb5f66bb3b6c2fd7eec1cdfee9cf3f68ef83487 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 6 Nov 2006 11:56:13 -0500 Subject: [PATCH] USB: Move private hub declarations out of public header file 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.
