Subject: [PATCH] brcmfmac: Add DMI nvram filename quirk for Voyo winpad A15 tablet
Git-commit: a338c874d3d9d2463f031e89ae14942929b93db6
Patch-mainline: v5.12-rc1
References: git-fixes
The Voyo winpad A15 tablet contains quite generic names in the sys_vendor
and product_name DMI strings, without this patch brcmfmac will try to load:
rcmfmac4330-sdio.To be filled by O.E.M.-To be filled by O.E.M..txt
as nvram file which is a bit too generic.
Add a DMI quirk so that a unique and clearly identifiable nvram file name
is used on the Voyo winpad A15 tablet.
While preparing a matching linux-firmware update I noticed that the nvram
is identical to the nvram used on the Prowise-PT301 tablet, so the new DMI
quirk entry simply points to the already existing Prowise-PT301 nvram file.
