   4 Subject: [PATCH] brcmfmac: add support for bcm4339 chip with modalias
   5  sdio:c00v02D0d4339
   6
   7 The driver already supports the bcm4339 chipset but only for the variant
   8 that shares the same modalias as the bcm4335, ie. sdio:c00v02D0d4335.
   9 It turns out that there are also bcm4339 devices out there that have a
  10 more distiguishable modalias sdio:c00v02D0d4339.
