ACPI / PM: Blacklist Low Power S0 Idle _DSM for ThinkPad X1 Tablet(2016)
[ Upstream commit 855c1c2fce8bdbd796cba1d1456ca8f0e876c2f1 ] ThinkPad X1 Tablet(2016) is reported to have issues with the Low Power S0 Idle _DSM interface and since this machine model generally can do ACPI S3 just fine, and user would like to use S3 as default sleep model, add a blacklist entry to disable that interface for ThinkPad X1 Tablet(2016).
