Subject: [PATCH] iommu: remove variable cnt
Date: Mon, 24 Oct 2022 14:43:01 +0100 [thread overview]
Message-ID: <20221024134301.2158939-1-colin.i.king@gmail.com> (raw)
Variable cnt is just being incremented and it's never used
anywhere else. The variable and the increment are redundant so
remove it.
