I'm looking at cherry-picking this and following commits to 3.2:
652aa6a9ac4a hid-input/battery: add FEATURE quirk
0c47935c5b5c HID: add battery quirk for Apple Wireless ANSI
4cc854178214 HID: add battery quirk for Apple 2009_ISO keyboard
What I don't understand about this is:

why did this also remove quirks for two other device IDs? Are they all
part of the same physical device so that the other two quirks are
redundant? Or was this a mistake?
