From cfcabdcc2d5a810208e5bb3974121b7ed60119aa Mon Sep 17 00:00:00 2001 From: Stephen Hemminger Date: Tue, 9 Oct 2007 01:59:42 -0700 Subject: [NET]: sparse warning fixes Fix a bunch of sparse warnings. Mostly about 0 used as NULL pointer, and shadowed variable declarations. One notable case was that hash size should have been unsigned. Signed-off-by: Stephen Hemminger Signed-off-by: David S.
