commit 0c625ccfe6f754d0896b8881f5c85bcb81699f1f upstream.
There are at least 3 models of the HP x2 10 models:
Bay Trail SoC + AXP288 PMIC Cherry Trail SoC + AXP288 PMIC Cherry Trail SoC + TI PMIC
Like on the other HP x2 10 models we need to ignore wakeup for ACPI GPIO events on the external embedded-controller pin to avoid spurious wakeups on the HP x2 10 CHT + AXP288 model too.
This commit adds an extra DMI based quirk for the HP x2 10 CHT + AXP288 model, ignoring wakeups for ACPI GPIO events on the EC interrupt pin on this model. This fixes spurious wakeups from suspend on this model.
