From a45ff9dd3fec5d604f99b2665c40db26ce81ec0c Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Wed, 21 Jan 2026 15:27:14 -0600 Subject: [PATCH 01/39] checkpatch: Fix false DT_SPLIT_BINDING_PATCH warnings Patches which both remove and add/modify DT binding files are incorrectly flagged as needing to split the patch.

These nodes might not have actual memory reserved (via memblock), leading to drivers (e.g., ramoops) accessing unreserved memory and causing memory corruption. Restrict the scan to the "/reserved-memory" node to ensure created devices are correctly backed by reserved memory. This enforces specification compliance and avoids dangerous probing.

However, there is no helper that returns the actual of_device_id structure corresponding to the match, leading to code duplication in various drivers. Fix this by reworking of_machine_device_match() to return the actual match structure, and renaming it to of_machine_get_match(). Retain the old of_machine_device_match() functionality using a cheap static inline wrapper around the new of_machine_get_match() helper.

This is the case, for instance, of the LAN966x PCI device driver. Adding some more nodes in the device-tree overlay adds some more consumer/supplier relationship between devices instantiated from this overlay. Those fw_node consumer/supplier relationships are handled by fw_devlink and are created based on the device-tree parsing done by the of_fwnode_add_links() function. Those consumer/supplier links are needed in order to ensure a correct PM runtime management and a correct removal order between devices. For instance, without those links a supplier can be removed before its consumers is removed leading to all kind of issue if this consumer still want the use the already removed supplier. The support for the usage of an overlay from a PCI driver has been added on x86 systems in commit 1f340724419ed ("PCI: of: Create device tree PCI host bridge node"). In the past, support for fw_devlink on x86 had been tried but this support has been removed in commit 4a48b66b3f52 ("of: property: Disable fw_devlink DT support for X86"). Indeed, this support was breaking some x86 systems such as OLPC system and the regression was reported in [0]. Instead of disabling this support for all x86 system, use a finer grain and disable this support only for the possible problematic subset of x86 systems (at least OLPC and CE4100). Those systems use a device-tree to describe their hardware. Identify those systems using key properties in the device-tree.

After that, the code still uses 'parent' to check for the presence of a property and to read a string property, leading to a use-after-free.
