From 60732292a135e8b8152858f219a563c05e9569e9 Mon Sep 17 00:00:00 2001 From: Sven Peter Date: Sun, 26 Nov 2023 17:20:09 +0100 Subject: [PATCH] iommu/apple-dart: Use readl instead of readl_relaxed for consistency While the readl_relaxed in apple_dart_suspend is correct the rest of the driver uses the non-relaxed variants everywhere and the single readl_relaxed is inconsistent and possibly confusing.
