All those lines are gone once my cfg80211 lands.
Do you know any way to make sparse moan about them?
BTW: the libertas firmware sometimes treat an SSID as a
zero-terminated string. There are some firmware commands that
accept just an u8[32] bytes for the SSID, but not an ssid_len,
e.g. in the CMD_802_11_AD_HOC_START command.
You therefore can't connect to the otherwise legitimate SSID of
TEST\0\0\0.
