Subject: brcmfmac: remove mac address validation from brcmf_net_attach()
X-Git-Url: https://openfabrics.org/gitweb/?a=commitdiff_plain;h=0b63cb71f1e6b74a6f68a9c7b10d823fd9914d0a;p=~shefty%2Frdma-dev.git

brcmfmac: remove mac address validation from brcmf_net_attach()

The mac_addr field in ifp object is always valid so no need to
validate.
