Subject: [PATCH 0/2] Fix s2idle resume on HP 15s-eq2xxx

HP 15s-eq2xxx has problems resuming from s2idle when IOMMU is enabled.
This is the same root cause as some Lenovo laptops had where IOMMU enabled
caused issues with NVME during s2idle resume from a problematic SMI.

To series fixes the issue by re-using the same quirk developed from the
older Lenovo laptops.

Mario Limonciello (2):
  platform/x86: Move s2idle quirk from thinkpad-acpi to amd-pmc
  platform/x86/amd: pmc: Apply nvme quirk to HP 15s-eq2xxx
