From 16e3423fc755cf9ddcceefaf70869311046928e2 Mon Sep 17 00:00:00 2001 From: Can Peng Date: Tue, 9 Dec 2025 15:15:13 +0800 Subject: [PATCH] iommu: simplify list initialization in iommu_create_device_direct_mappings() Use LIST_HEAD() to declare and initialize the 'mappings' list head in iommu_create_device_direct_mappings() instead of separate declaration and INIT_LIST_HEAD(). This simplifies the code by combining declaration and initialization into a single idiomatic form, improving readability without changing functionality.
