-stable review patch. If anyone has any objections, please let us know. ------------------ From: Jonathan Corbet The v4l2 API documentation for VIDIOC_ENUMSTD says: To enumerate all standards applications shall begin at index zero, incrementing by one until the driver returns EINVAL. The actual code, however, tests the index this way: if (index<=0 || index >= vfd->tvnormsize) { ret=-EINVAL; So any application which passes in index=0 gets EINVAL right off the bat - and, in fact, this is what happens to mplayer. So I think the following patch is called for, and maybe even appropriate for a 2.6.18.x stable release.
