Hi, Thorsten here, the Linux kernel's regression tracker.

Jarkko, I noticed a report about a regression in bugzilla.kernel.org
that appears to be related to i2c_designware [...]

After a bisection it turns out the regression is caused by a HID change
from Kenny, thus dropping Jarkko from the list of recipients and adding
Kenny and a few other appropriate folks and lists.

The culprit appears to be 7d6f065de37c31 ("HID: i2c-hid: Use address
probe to wake on resume") [v6.10-rc1].

For the rest, see the quote below or the linked ticket:

Just noticed that the touchscreen on my ASUS vivobook S14 stops
working after a suspend-to-idle. As this is something, I clearly
didn't have before, I tested every kernel version released in the
last six months and found the kernel, where the bug was introduced:
6.10. The last 6.9.12 is still working correctly. Since 6.10 all
kernel versions have the problem.

Some more info:

Hardware: ASUS Vivobook S14 (TP3402VA) Kernel working: up to 6.9.12 
Kernel defect: from 6.10 OS: nixos

I do not have much knowledge about the input devices. I tested that
i2c_hid_acpi seems to be relevant for the touchscreen (and also the
touchpad), as, when I remove it, both stop working. Reloading the
kernel module restores functionality (but NOT after a suspend-to-
idle!!!). Otherwise, I do not see any error messages or so. (Or do
not recognize them...)

Any help I can offer to identify the regression bug?

6.12-rc4 does not work either. The regression started with 6.10.
