Merge tag 'driver-core-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core updates from Greg KH: "Here is a small set of driver core changes for 6.13-rc1. Nothing major for this merge cycle, except for the two simple merge conflicts are here just to make life interesting. Included in here are: - sysfs core changes and preparations for more sysfs api cleanups that can come through all driver trees after -rc1 is out - fw_devlink fixes based on many reports and debugging sessions - list_for_each_reverse() removal, no one was using it! - last-minute seq_printf() format string bug found and fixed in many drivers all at once. - minor bugfixes and changes full details in the shortlog" * tag 'driver-core-6.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (35 commits) Fix a potential abuse of seq_printf() format string in drivers cpu: Remove spurious NULL in attribute_group definition s390/con3215: Remove spurious NULL in attribute_group definition perf: arm-ni: Remove spurious NULL in attribute_group definition driver core: Constify bin_attribute definitions sysfs: attribute_group: allow registration of const bin_attribute firmware_loader: Fix possible resource leak in fw_log_firmware_info() drivers: core: fw_devlink: Fix excess parameter description in docstring driver core: class: Correct WARN() message in APIs class_(for_each|find)_device() cacheinfo: Use of_property_present() for non-boolean properties cdx: Fix cdx_mmap_resource() after constifying attr in ->mmap() drivers: core: fw_devlink: Make the error message a bit more useful phy: tegra: xusb: Set fwnode for xusb port devices drm: display: Set fwnode for aux bus devices driver core: fw_devlink: Stop trying to optimize cycle detection logic driver core: Constify attribute arguments of binary attributes sysfs: bin_attribute: add const read/write callback variants sysfs: implement all BIN_ATTR_* macros in terms of __BIN_ATTR() sysfs: treewide: constify attribute callback of bin_attribute::llseek() sysfs: treewide: constify attribute callback of bin_attribute::mmap() ...
