Subject: platform/x86: Add s2idle quirk for more Lenovo laptops
From: David Lazar <dlazar@xxxxxxxxx>
commit 3bde7ec13c971445faade32172cb0b4370b841d9 upstream.
When suspending to idle and resuming on some Lenovo laptops using the
Mendocino APU, multiple NVME IOMMU page faults occur, showing up in
dmesg as repeated errors:
nvme 0000:01:00.0: AMD-Vi: Event logged [IO_PAGE_FAULT domain=0x000b
address=0xb6674000 flags=0x0000]
The system is unstable afterwards.
Applying the s2idle quirk introduced by commit 455cd867b85b ("platform/x86:
thinkpad_acpi: Add a s2idle resume quirk for a number of laptops")
allows these systems to work with the IOMMU enabled and s2idle
resume to work.
