Re: [PATCH net] wireless/nl80211: fix wdev_id may be used uninitialized

Build currently fails with -Werror=maybe-uninitialized set:

net/wireless/nl80211.c: In function '__cfg80211_wdev_from_attrs':
net/wireless/nl80211.c:124:44: error: 'wdev_id' may be used
uninitialized in this function [-Werror=maybe-uninitialized]

Really, build fails? Is -Werror enabled by default now? I hope not.

Don't think so. But we (Red Hat) build all our kernels with a fair
amount of extra error-checking enabled.
