The first patch reverts commit 0e6b6dedf168 ("Revert "ACPI: EC: Evaluate orphan _REG under EC device") that will not be necessary after making the changes in the last patch. The second patch modifies acpi_execute_reg_methods() to take an additional "depth" argument that will be needed doing forward. The last patch moves the _REG evaluation for EC operation regions beyond the EC device scope to acpi_bus_attach() so it is only evaluated if the device object holding the EC operation region is present. Thanks!
