+Subject: [PATCH] ACPICA: AML Parser: ignore control method status in
+ module-level code
+
+Previous change in the AML parser code blindly set all non-successful
+dispatcher statuses to AE_OK. This approach is incorrect because
+successful control method invocations from module-level return
+AE_CTRL_TRANSFER. Overwriting AE_OK to this status causes the AML
+parser to think that there was no return value from the control
+method invocation.
+
+fixes: 73c2a01c52b6 (ACPICA: AML Parser: ignore dispatcher error status during table load)
