Oh, cool.
Did not know of these parameters...

Device: 00:02.0
Class:  VGA compatible controller [0300]
Vendor: Intel Corporation [8086]
Device: 2nd Generation Core Processor Family Integrated Graphics
Controller [0116]
SVendor:        Samsung Electronics Co Ltd [144d]
SDevice:        Device [c0c7]
Rev:    09

...together with the pasted code-snippet, it is clear to me!

Thanks for the explanation and hints!
