Subject: [patch 1/2] iommu/mediatek: signedness bug in probe function
Date: Wed, 02 Mar 2016 10:10:06 +0000	[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')
