Subject: [PATCH] platform/x86: thinkpad_acpi: Add LED_RETAIN_AT_SHUTDOWN to led_class_devs
Git-commit: e518704d634fe3205903da6cbe97debf34885812
Patch-mainline: v5.17-rc1
References: bsc#1210050
Add the LED_RETAIN_AT_SHUTDOWN flag to the registered led_class_devs so
that the LEDs do not get turned-off when reloading the driver and thus so
that they also stay under default EC control when reloading the driver,
unless explicitly overridden by the user.
