leds: class: Make led_remove_lookup() NULL-aware

2026-04-09T12:49:19+00:00

It is a usual pattern in the kernel to make releasing functions be NULL-aware so they become a no-op. This helps reducing unneeded checks in the code where the given resource is optional.

leds: Kconfig: Drop unneeded dependency on OF_GPIO

2026-03-26T12:03:15+00:00

OF_GPIO is selected automatically on all OF systems. Any symbols it controls also provide stubs so there's really no reason to select it explicitly.

leds: lm3642: Use guard to simplify locking

2026-03-26T11:25:28+00:00

The mutex_lock()/mutex_unlock() pattern requires explicitly pairing lock and unlock calls. Use guard(mutex) instead so the lock is automatically released when the scope exits. Convert to guard(mutex) in lm3642_torch_brightness_set(), lm3642_strobe_brightness_set(), and lm3642_indicator_brightness_set(). Add #include to support scoped guards.

leds: core: Implement fallback to software node name for LED names

2026-03-26T09:31:44+00:00

If a software node defining an LED is missing explicit 'label', 'color', or 'function' properties, led_compose_name() currently fails with -EINVAL, because fallback to using node name in place of LED name/label is only implemented for OF nodes. Implement similar fallback for software nodes. Unlike OF nodes, which use the short 'name' attribute of the device tree node to avoid including the address block, use fwnode_get_name() directly since swnodes do not include an address block and always have a valid name.

leds: lp8860: Do not always program EEPROM on probe

2026-03-10T09:23:15+00:00

The EEPROM has limited writes and the contents might have factory set values that should not be changed. The values currently written by this driver are just one example of values, but might not be correct for many use-cases. Do not overwrite the EEPROM with these example values every probe. At some point it would be better to populate the content of the EEPROM based on a configuration provided by the user and check that the values in EEPROM are not already the same to avoid unneeded write cycles. That configuration would depend on how the device is used on the board to which it is attached, for that Device Tree might be the right way. Until a method can be devised, gate the EEPROM writing behind a module param.

leds: lp8860: Remove unused read of STATUS register

This register is read but the contents are never checked, remove the read until we add status checking. While here add an error message should the preceding fault check fail. Signed-off-by: Andrew Davis Link: https://patch.msgid.link/20260305203706.841384-4-afd@ti.com Signed-off-by: Lee Jones
