[1.] One line summary of the problem: Touchscreen does not work, dmesg
shows errors "i2c_hid i2c-ELAN0732:00: failed to reset device",
"i2c_hid i2c-ELAN0732:00: can't add hid device: -61", and "i2c_hid:
probe of i2c-ELAN0732:00 failed with error -61" occur during boot.

-61 is -ENODATA, which is raised when we timed-out when waiting for
the interrupt line.

To confirm this, please provide a dmesg from the boot with
i2c_hid.debug=1 appended to the kernel command line.

[2.] Full description of the problem/report: This is on an HP Eny x360
M6-AR004DX laptop with 7th-generation AMD FX CPU. The touchscreen is
not recognized at all; it appears the screen is using GPIO interrupts
as I have to build with AMD GPIO support to receive these errors,
otherwise I see a "failed to get GPIO interrupt" error.

So this is more likely either a failure of us retrieving the GPIO, or
a misconfiguration of those. I'd be interested if you could share the
output of acpidump (as root) as well.

Cheers,
Benjamin
