From fca5b78511e98bdff2cdd55c172b23200a7b3404 Mon Sep 17 00:00:00 2001 From: Barak Biber Date: Thu, 1 Aug 2024 09:26:04 -0300 Subject: iommu: Restore lost return in iommu_report_device_fault() When iommu_report_device_fault gets called with a partial fault it is supposed to collect the fault into the group and then return. Instead the return was accidently deleted which results in trying to process the fault and an eventual crash. Deleting the return was a typo, put it back.
