3.2.80-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Sudip Mukherjee <sudip@xxxxxxxxxxxxxxx>
commit ea32f065bd3e3e09f0bcb3042f1664caf6b3e233 upstream.
On error we jumped to the error label and returned the error code but we
missed releasing sinfo.
Fixes: 5fe74014172d ("mac80211: avoid excessive stack usage in sta_info")
Reviewed-by: Julian Calaby <julian.calaby@xxxxxxxxx>

[bwh: Backported to 3.2: there's no out_err label but there is another
error case that would leak sinfo]
