From 8c209e6782ca0e3046803fc04a5ac01c8c10437a Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 6 Mar 2009 21:31:03 -0800 Subject: USB: make actual_length in struct urb field u32 actual_length should also be a u32 and not a signed value. This patch changes this field to be 'u32' to prevent any potential negative conversion and comparison errors. This triggered a few compiler warning messages when these fields were being used with the min macro, so they have also been fixed up in this patch.
