The UX360CA has a WMI device id 0x00060062, which reports whether the
lid is flipped in tablet mode (1) or in normal laptop mode (0).
This commit adds a quirk (quirk_asus_use_lid_flip_devid) for devices on
which this WMI device should be used to figure out the SW_TABLET_MODE
state, as opposed to the quirk_asus_use_kbd_dock_devid.
It is assumed other UX360* models have the same WMI device. As such, the
quirk is applied to devices with DMI_MATCH(DMI_PRODUCT_NAME, "UX360").
More devices with this feature need to be tested and added accordingly.
The reason for using a whitelist via the quirk mechanism is that the new
WMI device (0x00060062) is also present on some models which do not have
a 360 degree hinge (at least FX503VD and GL503VD from Hans' DSTS
collection) and therefore its presence cannot be relied on.
This patch is a followup to "platform/x86: asus-wmi: Fix SW_TABLET_MODE
always reporting 1 on many different models" by Hans de Goede.

Note the default (quirk_asus_unknown) quirks set:
.wmi_backlight_set_devstate = true,
So you're changing that to false for all devices using that
quirk now. I did not set this quirk for the transformer devices,
since the quirk has to do with the handling of Fn + F7 (display off hotkey)
by the embedded-controller. Since on transformer devices the keyboard is
an USB device and not handled by the embedded-controller they do not need
the wmi_backlight_set_devstate quirk, so I left it out. Chances are that
your UX360 does need it. The purpose of the quirk is to make the embbedded
controller send a KEY_DISPLAY_OFF event on FN + F7 and have it not do anything
else (like turning off the backlight by itself).
TL;DR: you should probably add: .wmi_backlight_set_devstate = true,
to your new quirk_asus_use_lid_flip_devid quirk.

Of course. I didn't notice that. Thank you.
Should I send a v2 right away, or do I wait for other potential
comments?
