So what?

I will repeat: similar bugs were already fixed here:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=782eea0c89f7d071d6b56ecfa1b8b0c81164b9be
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a69982c37cd0586e6832268155349301b87f2e35
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=4cb786180dfb5258ff3111181b5e4ecb1d4a297b

So we just need to add similar patch. I. e. something similar to this:

+		.matches = {
+			DMI_MATCH(DMI_BOARD_NAME, "NL5xRU"),
+		},
+		.driver_data = &(struct acpi_gpiolib_dmi_quirk) {
+			.ignore_wake = "ELAN0415:00@9",
+		},

Remaining question: how should I get these strings on my system? "NL5xRU" and "ELAN0415:00@9"?

DMI_MATCH(DMI_BOARD_NAME, *) will match to /sys/class/dmi/id/board_name (/sys/class/dmi/id/ also contains a lot of other strings to identify your device e.g. /sys/class/dmi/id/sys_vendor which can be matched with DMI_MATCH(DMI_SYS_VENDOR, *))

How to get "ELAN0415:00@9" is somewhere buried in here https://gitlab.freedesktop.org/drm/amd/-/issues/1722#note_1725104

Best regards,

Werner
