This is what's both in the DSDT
Device (WLN)
{
[...]
Name (BDFE, "BDF_LES790")
and kvalo's board-2.bin for this machine:
$ strings board-2.bin | grep LES
bus=pci,vendor=17cb,device=1107,subsystem-vendor=17aa,subsystem-device=e0e9,qmi-chip-id=2,qmi-board-id=255,variant=LES790
I don't think we can hand-pick these strings, they come from whoever
decided upon them and fed them into ACPI tables and QC's binaries.
