From 2dbbcce1f8dd3cd3cbb95717fd73d771a6c60718 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sat, 11 May 2019 13:41:35 +0100 Subject: [PATCH] iommu/amd: Remove redundant assignment to variable npages The variable npages is being initialized however this is never read and later it is being reassigned to a new value. The initialization is redundant and hence can be removed.
