Help with compiling module patch for ACPI driver
 

Newbie to Linux having installed Linux Mint 19.3 Cinnamon 64-bit on a 12-year old Lenovo ThinkPad T61 a little over a week ago.

I am getting the ACPI error listed in this German-speaking forum and on post 11, there appears to be a patch to thinkpad_acpi to stop these error messages from appearing during boot:

Direct link to specific post in the thread with the fix I'm trying to implement:

Being new to Linux, how would I compile the code he has and get it loaded?

He has this command listed but I know there's more to this:

$ make -C /usr/src/linux-headers-$(uname -r) M=$(dirname $(realpath "$0"))

Any help would be greatly appreciated

Is asking a follow-up question on that forum not an option? Seems like the subject has already been covered there.

It's a German forum and I do not speak German.

I was hoping there is perhaps a standard method for compiling such patches that it wouldn't necessarily require specific instructions.

I think I'm just going to ignore the ACPI messages, it's not affecting functionality as far as I can tell.

On Ubuntu 22.04, it works fine with below command.

make -C /lib/modules/$(uname -r)/build M=$(shell pwd) modules
