Smatch complains about this code:
drivers/net/wireless/broadcom/brcm80211/brcmfmac/core.c:335 brcmf_rx_hdrpull()
error: we previously assumed '*ifp' could be null (see line 333)
The problem is that we recently changed these from "ifp" to "*ifp" but
there was one that we didn't update.
- if (ret || !ifp || !ifp->ndev) {
+ if (ret || !(*ifp) || !(*ifp)->ndev) {
if (ret != -ENODATA && ifp)
^^^
- ifp->stats.rx_errors++;
+ (*ifp)->stats.rx_errors++;
I have updated it to *ifp as well. We always call this function is a
non-NULL "ifp" pointer, btw.
Fixes: c462ebcdfe42 ('brcmfmac: create common function for handling brcmf_proto_hdrpull()')
