Rong Zhang d2a6a3543f platform/x86: ideapad-laptop: Fix kbd backlight not remembered among boots ... commit e10981075a upstream. On some models supported by ideapad-laptop, the HW/FW can remember the state of keyboard backlight among boots. However, it is always turned off while shutting down, as a side effect of the LED class device unregistering sequence. This is inconvenient for users who always prefer turning on the keyboard backlight. Thus, set LED_RETAIN_AT_SHUTDOWN on the LED class device so that the state of keyboard backlight gets remembered, which also aligns with the behavior of manufacturer utilities on Windows.
