[PATCH 2/3] wifi: brcmfmac: avoid invalid list operation when vendor attach fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



When the brcmf_fwvid_attach() fails the driver instance is not added
to the vendor list. Hence we should not try to delete it from that
list when the brcmf_fwvid_detach() function is called in cleanup path.
