From: Dan Carpenter <dan.carpenter@oracle.com> [ Upstream commit 216b44000ada87a63891a8214c347e05a4aea8fe ] The brcmu_pkt_buf_free_skb() function frees "pkt" so it leads to a static checker warning: drivers/net/wireless/broadcom/brcm80211/brcmfmac/sdio.c:1974 brcmf_sdio_readframes() error: dereferencing freed memory 'pkt' It looks like there was supposed to be a continue after we free "pkt".
