[PATCH AUTOSEL 5.4 15/23] ACPI: EC: Remove duplicate ThinkPad X1 Carbon 6th entry from DMI quirks

[Sasha Levin]

From: Hans de Goede <hdegoede@redhat.com>

[ Upstream commit 0dd6db359e5f206cbf1dd1fd40dd211588cd2725 ]

Somehow the "ThinkPad X1 Carbon 6th" entry ended up twice in the
struct dmi_system_id acpi_ec_no_wakeup[] array. Remove one of
the entries.

[PATCH AUTOSEL 5.4 16/23] ACPI: PM: save NVS memory for Lenovo G40-45

[Sasha Levin]

From: Manyi Li <limanyi@uniontech.com>

[ Upstream commit 4b7ef7b05afcde44142225c184bf43a0cd9e2178 ]

[821d6f0359b0614792ab8e2fb93b503e25a65079] is to make machines
produced from 2012 to now not saving NVS region to accelerate S3.

But, Lenovo G40-45, a platform released in 2015, still needs NVS memory
saving during S3. A quirk is introduced for this platform.
