ath6kl: Fix possible unaligned memory access in ath6kl_get_rsn_capab()
alignment is not taken care in accessing pairwise cipher and AKM suite count which are parsed from rsn ie. Fix this alignment issue. Reported-by: Joe Perches <joe@perches.com> Signed-off-by: Vasanthakumar Thiagarajan <vthiagar@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
