    Merge tag 'driver-core-7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core

    Pull driver core updates from Danilo Krummrich:
     "Bus:

       - Ensure bus->match() is consistently called with the device lock
         held

       - Improve type safety of bus_find_device_by_acpi_dev()

      Devtmpfs:

       - Parse 'devtmpfs.mount=' boot parameter with kstrtoint() instead of
         simple_strtoul()

       - Avoid sparse warning by making devtmpfs_context_ops static

      IOMMU:

       - Do not register the qcom_smmu_tbu_driver in arm_smmu_device_probe()

      MAINTAINERS:

       - Add the new driver-core mailing list (driver-core@lists.linux.dev)
         to all relevant entries

       - Add missing tree location for "FIRMWARE LOADER (request_firmware)"

       - Add driver-model documentation to the "DRIVER CORE" entry

       - Add missing driver-core maintainers to the "AUXILIARY BUS" entry

      Misc:

       - Change return type of attribute_container_register() to void; it
         has always been infallible

       - Do not export sysfs_change_owner(), sysfs_file_change_owner() and
         device_change_owner()

       - Move devres_for_each_res() from the public devres header to
         drivers/base/base.h

       - Do not use a static struct device for the faux bus; allocate it
         dynamically

      Revocable:

       - Patches for the revocable synchronization primitive have been
         scheduled for v7.0-rc1, but have been reverted as they need some
         more refinement

      Rust:

       - Device:
          - Support dev_printk on all device types, not just the core Device
            struct; remove now-redundant .as_ref() calls in dev_* print
            calls

       - Devres:
          - Introduce an internal reference count in Devres<T> to avoid a
            deadlock condition in case of (indirect) nesting

       - DMA:
          - Allow drivers to tune the maximum DMA segment size via
            dma_set_max_seg_size()

       - I/O:
          - Introduce the concept of generic I/O backends to handle
            different kinds of device shared memory through a common
            interface.

            This enables higher-level concepts such as register
            abstractions, I/O slices, and field projections to be built
            generically on top.

            In a first step, introduce the Io, IoCapable<T>, and IoKnownSize
            trait hierarchy for sharing a common interface supporting offset
            validation and bound-checking logic between I/O backends.

          - Refactor MMIO to use the common I/O backend infrastructure

       - Misc:
          - Add __rust_helper annotations to C helpers for inlining into
            Rust code

          - Use "kernel vertical" style for imports

          - Replace kernel::c_str! with C string literals

          - Update ARef imports to use sync::aref

          - Use pin_init::zeroed() for struct auxiliary_device_id and
            debugfs file_operations initialization

          - Use LKMM atomic types in debugfs doc-tests

          - Various minor comment and documentation fixes

       - PCI:
          - Implement PCI configuration space accessors using the common I/O
            backend infrastructure

          - Document pci::Bar device endianness assumptions

       - SoC:
          - Abstractions for struct soc_device and struct soc_device_attribute

          - Sample driver for soc::Device"
