Linus Torvalds c6e62d002b Driver core changes for 7.0-rc1
- 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
