Hi Johannes,
I played with crosstool-ng to compile test our driver for a number of
platforms that it is supposed to work on. The gcc version is 4.7.2.
*mips*:
CC [M] net/mac80211/tx.o
net/mac80211/tx.c: In function 'ieee80211_subif_start_xmit':
net/mac80211/tx.c:1797:22: error: 'chanctx_conf' may be used
uninitialized in this function [-Werror=maybe-uninitialized]

Yeah it seems to randomly throw this warning under certain
circumstances, sometimes gcc doesn't seem to be able to prove that in
fact it *isn't* used uninitialized.
I think we should just leave the warning though, anything else I could
come up with to suppress it would just cause real ones to be suppressed
as well if somebody changes this code.
