The consequence of this is that the "timer" trigger would not cause the LED to blink if given default parameters. This problem exists since 2.6.26-rc1. To fix it, switch the deferred LED work handling to use the thinkpad-acpi-specific LED status (off/on/blink) directly. This also makes the code easier to read, and to extend later.
