Tested this patch based on latest mainline kernel at commit f804b3159482 ("Merge
tag 'linux-watchdog-5.10-rc1' of git://www.linux-watchdog.org/linux-watchdog").
We have some laptops equipped with Tiger Lake chips and such configuration that
hit the same issue. They all could be fixed by this patch.
Thank you
