Hi,

I'd like to file a bug in the latest commit: 
b6f4c524e0fe8f2d50b0a2f849e022adef76c6cc

The file backports/api_version.patch rejects to patch the 
linux/drivers/media/v4l2-core/v4l2-ioctl.c because of wrong line numbers 
and because the code doesn't match.


This is your code:
-----------------------------------------------------------------------
--- a/drivers/media/v4l2-core/v4l2-ioctl.c
+++ b/drivers/media/v4l2-core/v4l2-ioctl.c
@@ -1009,7 +1009,7 @@ static int v4l_querycap(const struct 
v4l2_ioctl_ops *ops,
  	struct v4l2_capability *cap = (struct v4l2_capability *)arg;
  	int ret;

-	cap->version = LINUX_VERSION_CODE;
+	cap->version = V4L2_VERSION;

  	ret = ops->vidioc_querycap(file, fh, cap);

-----------------------------------------------------------------------

This should be there:

-	cap->version = LINUX_VERSION_CODE;
+	cap->version = V4L2_VERSION;
  	return ops->vidioc_querycap(file, fh, cap);
  }

-----------------------------------------------------------------------

In the C file there's no ret variable and all the code is moved 
somewhere else, but it's not @@ line 1009.

The diff file is attached.

When I hacked the patch file, I built everything.

Regards.
