Message-Id: <20071202173329.15374.4223.sendpatchset@thinktank.campus.ltu.se>
Date: Sun, 2 Dec 2007 18:46:55 +0100 (MET)
From: Richard Knutsson <ricknu-0@...dent.ltu.se>
To: hverkuil@...all.nl, mchehab@...radead.org
Cc: v4l-dvb-maintainer@...uxtv.org, linux-kernel@...r.kernel.org,
Richard Knutsson <ricknu-0@...dent.ltu.se>
Subject: [PATCH 1/2] ivtv: Some general fixes
Fix "warning: Using plain integer as NULL pointer".
Remove a gcc-2.95 requirement.
Convert 'x < y ? x : y' to use min() instead.
Signed-off-by: Richard Knutsson <ricknu-0@...dent.ltu.se>
---
Compile-tested on i386 with "allyesconfig" and "allmodconfig".
