From 7d6e30dfcc723b8fe86e5413640ac229a37310ab Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Wed, 10 Aug 2022 16:23:33 +0200 Subject: wifi: brcmfmac: Add DMI nvram filename quirk for Chuwi Hi8 Pro tablet The Chuwi Hi8 Pro tablet contains quite generic names in the sys_vendor and product_name DMI strings, without this patch brcmfmac will try to load: "brcmfmac43430a0-sdio.Default string-Default string.txt" as nvram file which is way too generic. The Chuwi Hi8 Pro uses the same Ampak AP6212 module as the Chuwi Vi8 Plus and the nvram for the Vi8 Plus is already in linux-firmware, so point the new DMI nvram filename quirk to the Vi8 Plus nvram file.
