4 Subject: [PATCH] brcmfmac: use brcmf_chip_name() to store name in revinfo
5
6 The chip id can either be four or five digits. For the chip name either
7 the hexadecimal value needs to be taken (four digits) or the decimal
8 value (five digits). The function brcmf_chip_name() does this conversion
9 so use it to store the name in driver revision info.
