To fix a bug and address the reviewers' comments regarding the ACPI GPE refcounting patch, do the following additional changes: o Remove the second argument of acpi_ev_enable_gpe(), 'write_to_hardware', because it is not necessary any more. o Add the "bad parameter" test against 'type' in acpi_enable_gpe() and acpi_disable_gpe(). o Make acpi_enable_gpe() only check 'status' for runtime GPEs if acpi_ev_enable_gpe() was actually called. o Make acpi_disable_gpe() return 'status' returned by acpi_ev_disable_gpe() and fix a bug where ACPI_GPE_TYPE_WAKE and ACPI_GPE_TYPE_RUNTIME were exchanged by mistake. o Add comments explaining why acpi_set_gpe() is used by the ACPI EC driver.
