From d6623eea9abb43607621bd85fccaed6543a042c4 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Thu, 1 Oct 2020 12:39:00 +0100 Subject: [PATCH] x86/events/amd/iommu: Fix sizeof mismatch [ Upstream commit 59d5396a4666195f89a67e118e9e627ddd6f53a1 ] An incorrect sizeof is being used, struct attribute ** is not correct, it should be struct attribute *. Note that since ** is the same size as * this is not causing any issues. Improve this fix by using sizeof(*attrs) as this allows us to not even reference the type of the pointer.
