From f90580ca0133c533763a6cb3e632a21098a382df Mon Sep 17 00:00:00 2001 From: Ricardo Ribalda Date: Tue, 26 Nov 2013 05:31:42 -0300 Subject: [media] videodev2: Set vb2_rect's width and height as unsigned As discussed on the media summit 2013, there is no reason for the width and height to be signed. Therefore this patch is an attempt to convert those fields from __s32 to __u32.
