Any specific reason to use an Intel ACPI identifier? Why not use
"TIAS2563" ?
It looks the INT prefix is not reserved. (yet)INT8866 is in the ACPI.
I don't know why Lenovo uses this name.
I think it's more internal than intel.

Ouch, I hope they checked with Intel that this isn't an HID already in
use...

It's been de-facto reclaimed by Intel over the years, apparently using
INTC or INTL was too hard for some of my colleagues...
There are lots of INT devices in the kernel today, here's a small list
for sound/soc/codecs only
rt274.c: { "INT34C2", 0 },
rt286.c: { "INT343A", 0 },
rt298.c: { "INT343A", 0 },
ssm4567.c: { "INT343B", 0 },
Those INT values were added by Intel teams though, it's really odd to
see Lenovo use an INT-based HID. Should really use 104C2563 or something.
