[PATCH 4.9 119/177] iommu/mediatek: Fix driver name

From: Greg Kroah-Hartman
Date: Mon Dec 18 2017 - 11:19:38 EST


4.9-stable review patch. If anyone has any objections, please let me know.

------------------

From: Matthias Brugger <matthias.bgg@xxxxxxxxx>


[ Upstream commit 395df08d2e1de238a9c8c33fdcd0e2160efd63a9 ]

There exist two Mediatek iommu drivers for the two different
generations of the device. But both drivers have the same name
"mtk-iommu". This breaks the registration of the second driver:

Error: Driver 'mtk-iommu' is already registered, aborting...

Fix this by changing the name for first generation to
"mtk-iommu-v1".
