---8<------------------------------------------------------------ From: Dan Carpenter <[email protected]> commit 3a318426e09a9c9266fe6440842e11238f640a20 upstream. 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.')
