Pull driver core and debugfs updates from Greg KH: "Here is the big set of driver core and debugfs updates for 6.14-rc1. Included in here is a bunch of driver core, PCI, OF, and platform rust bindings (all acked by the different subsystem maintainers), hence the merge conflict with the rust tree, and some driver core api updates to mark things as const, which will also require some fixups due to new stuff coming in through other trees in this merge window. There are also a bunch of debugfs updates from Al, and there is at least one user that does have a regression with these, but Al is working on tracking down the fix for it. In my use (and everyone else's linux-next use), it does not seem like a big issue at the moment. Here's a short list of the things in here: - driver core rust bindings for PCI, platform, OF, and some i/o functions. We are almost at the "write a real driver in rust" stage now, depending on what you want to do. - misc device rust bindings and a sample driver to show how to use them - debugfs cleanups in the fs as well as the users of the fs api for places where drivers got it wrong or were unnecessarily doing things in complex ways. - driver core const work, making more of the api take const * for different parameters to make the rust bindings easier overall. - other small fixes and updates All of these have been in linux-next with all of the aforementioned merge conflicts, and the one debugfs issue, which looks to be resolved "soon"" * tag 'driver-core-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (95 commits) rust: device: Use as_char_ptr() to avoid explicit cast rust: device: Replace CString with CStr in property_present() devcoredump: Constify 'struct bin_attribute' devcoredump: Define 'struct bin_attribute' through macro rust: device: Add property_present() saner replacement for debugfs_rename() orangefs-debugfs: don't mess with ->d_name octeontx2: don't mess with ->d_parent or ->d_parent->d_name arm_scmi: don't mess with ->d_parent->d_name slub: don't mess with ->d_name sof-client-ipc-flood-test: don't mess with ->d_name qat: don't mess with ->d_name xhci: don't mess with ->d_iname mtu3: don't mess wiht ->d_iname greybus/camera - stop messing with ->d_iname mediatek: stop messing with ->d_iname netdevsim: don't embed file_operations into your structs b43legacy: make use of debugfs_get_aux() b43: stop embedding struct file_operations into their objects carl9170: stop embedding file_operations into their objects ...

leds: triggers: Constify 'struct bin_attribute'

The sysfs core now allows instances of 'struct bin_attribute' to be moved into read-only memory. Make use of that to protect them against accidental or malicious modifications.

leds: cht-wcove: Use devm_led_classdev_register() to avoid memory leak

2025-01-09T10:57:16Z

cht_wc_leds_probe() leaks memory when the second led_classdev_register() call in the for-loop fails as it does not call the cleanup function led_classdev_unregister() on the first device. Avoid this leak by calling devm_led_classdev_register().

leds: Add LED1202 I2C driver

2025-01-09T10:30:23Z

The output current can be adjusted separately for each channel by 8-bit analog (current sink input) and 12-bit digital (PWM) dimming control. The LED1202 implements 12 low-side current generators with independent dimming control. Internal volatile memory allows the user to store up to 8 different patterns, each pattern is a particular output configuration in terms of PWM duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but common to all patterns. Each device tree LED node will have a corresponding entry in /sys/class/leds with the label name. The brightness property corresponds to the per channel analog dimming, while the patterns[1-8] to the PWM dimming control.

leds: pwm-multicolor: Disable PWM when going to suspend

2024-12-17T15:04:46Z

This fixes suspend on platforms like stm32mp1xx, where the PWM consumer has to be disabled for the PWM to enter suspend. Another positive side effect is that active-low LEDs now properly turn off instead of going back to full brightness when they are set to 0.

leds: netxbig: Fix an OF node reference leak in netxbig_leds_get_of_pdata()

netxbig_leds_get_of_pdata() does not release the OF node obtained by of_parse_phandle() when of_find_device_by_node() fails. Add an of_node_put() call to fix the leak.
