What's going on? As I said in the cover-letter of v6 the platform patches were mainly there to document the usage of the new LED api. Since there were no changes to the api I did not post a v7 of the platform/x86 patches, also I've not yet tested the thinkpad changes as adjusted for the new LED api. Once the LED side is merged, I'll re-post the platform patches.

Make thinkpad_acpi call led_classdev_notify_brightness_hw_changed on the kbd_led led_classdev registered by thinkpad_acpi when the kbd backlight brightness is changed through the hotkey. This will allow userspace to monitor (poll) for brightness changes on these LEDs caused by the hotkey.
