ath9k_htc: check for underflow in ath9k_htc_rx_msg()
We check for overflow here, but we don't check for underflow so it causes a static checker warning. Fixes: fb9987d0f748 ('ath9k_htc: Support for AR9271 chipset.') Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
