Subject: [PATCH] wifi: iwlwifi: read BIOS PNVM only for non-Intel SKU
Git-commit: c868a189ecfe8cc0b3173c2eaa7f0b659326c151
Patch-mainline: v6.9-rc1
References: git-fixes
The driver is supposed to read the PNVM from BIOS only for non-Intel
SKUs. For Intel SKUs the OEM ID will be 0.
Read BIOS PNVM only when a non-Intel SKU is indicated.
Fixes: b99e32cbfdf6 ("wifi: iwlwifi: Take loading and setting of pnvm image out of parsing part")
