Nowadays many laptops have camera access keys, yet there is no usage codes mapped to them, even though it's introduced in HUTRR72. Start point of this patch series was adding it and making IdeaPads send it to userspace. But later I discovered that camera_power attribute of ideapad-laptop driver on my IdeaPad 520-15IKB doesn't work, so I can't toggle it with that. I managed to find a way to check whether an IdeaPad supports camera_power attribute (which sends VPCCMD_W_CAMERA to EC), don't expose it to sysfs so userspace will know that it can't toggle camera access via camera_power, in my case, after receiving KEY_CAMERA_ACCESS_TOGGLE. Along the way I discovered that old IdeaPads, like S10-3, may not be able to toggle their touchpad as a regression of a commit aimed for newer IdeaPads, so I reverted it. Also I noticed that I can get/set the state of my keyboard light, so one of the patches also adds supports for this kind of keyboard lights, which I call "partially supported keyboard lights". I expect that commit to add keyboard light support for 520-15IKB, 330-17ICH, 5 (15) and more. Currently only tested on 520-15IKB.
