Subject: [patch 1/2] iommu/mediatek: signedness bug in probe function
Date: Wed, 2 Mar 2016 13:10:06 +0300 [thread overview]
Message-ID: <20160302101006.GF5533@mwanda> (raw)
"larb_nr" needs to be signed for the error handling to work. "i" can
be int as well.
Fixes: 0df4fabe208d ('iommu/mediatek: Add mt8173 IOMMU driver')
