[PATCH] brcmfmac: Fix memory leak in brcmf_p2p_create_p2pdev()

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

 



In the implementation of brcmf_p2p_create_p2pdev() the allocated memory
for p2p_vif is leaked when the mac address is the same as primary
interface. To fix this, go to error path to release p2p_vif via
brcmf_free_vif().

Fixes: cb746e47837a ("brcmfmac: check p2pdev mac address uniqueness")
