From 737c097b9aed92906b4bb9f90f05eb4d5696f572 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Tue, 4 Sep 2012 10:08:01 -0300 Subject: [PATCH] [media] v4l2-ioctl.c: fix overlay support The vidioc_overlay op needs an unsigned int, not an unsigned int pointer. So we need a small function that dereferences the unsigned int pointer.
