Subject: [GIT PULL] Driver core changes for 7.2-rc1
Date: Sat, 13 Jun 2026 19:52:42 +0200 [thread overview]
Message-ID: <DJ84318BOPGD.25U77KZQOCNFP@kernel.org> (raw)
Hi Linus,
Please pull these driver-core changes.
All commits have been in linux-next for at least a few rounds; the Rust-native
device driver lifetime series has been shared with the DRM tree via a signed
tag.

software node: allow passing reference args to PROPERTY_ENTRY_REF() (2026-06-10 00:58:04 +0200)
----------------------------------------------------------------
Driver core changes for 7.2-rc1
- deferred probe:
- Fix race where deferred probe timeout work could be permanently
canceled by using mod_delayed_work()
- Fix missing jiffies conversion in deferred_probe_extend_timeout()
- Guard timeout extension with delayed_work_pending() to prevent
premature firing
- Use system_percpu_wq instead of the deprecated system_wq
- Update deferred_probe_timeout documentation
- device:
- Replace direct struct device bitfield access (can_match, dma_iommu,
dma_skip_sync, dma_ops_bypass, state_synced, dma_coherent,
of_node_reused, offline, offline_disabled) with flag-based
accessors using bit operations
- Reject devices with unregistered buses
- Delete unused DEVICE_ATTR_PREALLOC()
- Add low-level device attribute macros with const show/store
callbacks, allowing device attributes to reside in read-only memory
- Move core device attributes to read-only memory
- Constify group array pointers in driver_add_groups() /
driver_remove_groups(), struct bus_type, and struct device_driver
- device property:
- Fix fwnode reference leak in fwnode_graph_get_endpoint_by_id()
- Initialize all fields of fwnode_handle in fwnode_init()
- Provide swnode_get()/swnode_put() wrappers around kobject_get/put()
- Allow passing struct software_node_ref_args pointers directly to
PROPERTY_ENTRY_REF()
- driver_override:
- Migrate amba, cdx, vmbus, and rpmsg to the generic driver_override
infrastructure, fixing a UAF from unsynchronized access to
driver_override in bus match() callbacks
- Remove the now-unused driver_set_override()
- firmware loader:
- Fix recursive lock deadlock in device_cache_fw_images() when async
work falls back to synchronous execution
- Fix device reference leak in firmware_upload_register()
- platform:
- Pass KBUILD_MODNAME through the platform driver registration macro
to create module symlinks in sysfs for built-in drivers; move
module_kset initialization to a pure_initcall and tegra cbb
registration to core_initcall to ensure correct ordering
- Pass THIS_MODULE implicitly through a coresight_init_driver() macro
- sysfs:
- Upgrade OOB write detection in sysfs_kf_seq_show() from printk to
WARN
- Add return value clamping to sysfs_kf_read()
- Rust:
- ACPI:
- Fix missing match data for PRP0001 by exporting
acpi_of_match_device()
- Auxiliary:
- Replace drvdata() with dedicated registration data on
auxiliary_device. drvdata() exposed the driver's bus device
private data beyond the driver's own scope, creating ordering
constraints and forcing the data to outlive all registrations
that access it. Registration data is instead scoped structurally
to the Registration object, making lifecycle ordering enforced
by construction rather than convention.
- Rust-native device driver lifetimes (HRT):
- Allow Rust device drivers to carry a lifetime parameter on their
bus device private data, tied to the device binding scope -- the
interval during which a bus device is bound to a driver. Device
resources like pci::Bar<'a> and IoMem<'a> can be stored directly
in the driver's bus device private data with a lifetime bounded
by the binding scope, so the compiler enforces at build time that
they do not outlive the binding. This removes Devres indirection
from every access site and eliminates try_access() failure paths
in destructors.
Bus driver traits use a Generic Associated Type (GAT)
Data<'bound> to introduce the lifetime on the private data,
rather than parameterizing the Driver trait itself. Auxiliary
registration data, where the lifetime is not introduced by a
trait callback but must be threaded through Registration, uses
the ForLt trait (a type-level abstraction for types generic over
a lifetime).
- Misc:
- Fix DT overlayed devices not probing by reverting the broken
treewide overlay fix and re-running fw_devlink consumer pickup when
an overlay is applied to a bound device
- Use root_device_register() for faux bus root device; add sanity
check for failed bus init
- Fix dev_has_sync_state() data race with READ_ONCE() and move it to
base.h
- Avoid spurious device_links warning when removing a device while
its supplier is unbinding
- Switch ISA bus to dynamic root device
- Fix suspicious RCU usage in kernfs_put()
- Remove devcoredump exit callback
- Constify devfreq_event_class
