brcmfmac: fix memory leak in brcmf_fill_bss_param
This function is called from get_station callback which means that every time user space was getting/dumping station(s) we were leaking 2 KiB. Signed-off-by: Rafał Miłecki <rafal@milecki.pl> Fixes: 1f0dc59a6de ("brcmfmac: rework .get_station() callback") Cc: stable@vger.kernel.org # 4.2+ Acked-by: Arend van Spriel <arend.vanspriel@broadcom.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
