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.
