Can someone comment on what exactly is being printed for the driver version :)? Does the reporting anyhow correlated with what oneAPI `sycl-ls reports`:
```
sycl-ls
[level_zero:gpu][level_zero:0] Intel(R) oneAPI Unified Runtime over Level-Zero V2, Intel(R) Arc(TM) B580 Graphics 20.1.0 [1.15.38308+1]
[level_zero:gpu][level_zero:1] Intel(R) oneAPI Unified Runtime over Level-Zero V2, Intel(R) UHD Graphics 770 12.2.0 [1.15.38308+1]
```
