From 2e9e4f1182a001f263a2908c5f0115eacb3bd104 Mon Sep 17 00:00:00 2001 From: Philipp Zabel Date: Mon, 30 Sep 2013 10:34:50 -0300 Subject: [PATCH] [media] coda: prefix v4l2_ioctl_ops with coda_ instead of vidioc_ Moving the ioctl handler callbacks into the coda namespace helps tremendously to make sense of backtraces.
