From 166983cdfbb2779bec98de89927669ed4c9ff8f2 Mon Sep 17 00:00:00 2001 From: Ian Armstrong Date: Sun, 21 Oct 2007 08:09:10 -0300 Subject: [PATCH] V4L/DVB (6714): ivtv: yuv frame parameter fix Inadvertently missed a line when converting code to new hardware buffering method. In some circumstances, this would lead to a frame being displayed using parameters belonging to another frame.
