    Subject[PATCH AUTOSEL 5.11 22/67] brcmfmac: Add DMI nvram filename quirk for Predia Basic tablet
    Date
    From: Hans de Goede <hdegoede@redhat.com>

    [ Upstream commit af4b3a6f36d6c2fc5fca026bccf45e0fdcabddd9 ]

    The Predia Basic tablet contains quite generic names in the sys_vendor and
    product_name DMI strings, without this patch brcmfmac will try to load:
    brcmfmac43340-sdio.Insyde-CherryTrail.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 Predia Basic tablet.
