media: vidioc-querycap: use a more realistic value for KERNEL_VERSION (d39d7085) · Commits · 戴 / test

In the past, V4L2 versions were 0.x.y, but that changed years ago. Since Kernel 3.1, however, the numbering schema was changed to match the Kernel version. However, the presented example still uses the old numerating schema, with is a misleading information. So, update it to the new schema. Signed-off-by:
