ACPI: EC: Avoid evaluating _REG for non-functional operation regions
|

Hi Everyone, The purpose of this series is to address issues reported here: https://lore.kernel.org/linux-acpi/1f76b7e2-1928-4598-8037-28a1785c2d13@redhat.com/ and related to evaluating _REG for EC operation regions that are not expected to be used (for example, because they reside in the scopes of ACPI device objects whose _STA returns 0). 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!
