Subject: [media] videodev2.h: Fix VIDIOC_QUERYMENU ioctl regression Author: Hans Verkuil <[email protected]> Date: Tue Apr 17 08:41:58 2012 -0300 Fixes a regression in VIDIOC_QUERYMENU introduced when the __s64 value field was added to the union. On a 64-bit system this will change the size of this v4l2_querymenu structure from 44 to 48 bytes, thus breaking the ABI. By adding the packed attribute it is working again. Tested on both 64 and 32 bit systems.
