Correct but this is an attempt to fix an issue with the existing code where wifi/generic can handle an integrated WiFi (CNVi) device as a PCIe WiFi device and a Generic device (refer to wifi_generic_enable()).
I have verified this patch for both the cases. Refer to SSDT snippet at the end of the commit message ("SSDT when CNVi").
