ACPICA: Dispatcher: Fix a mutex issue for method auto serialization
ACPICA commit fd305eda14f1a1e684edef4fac53f194bf00ed3f This patch fixes an issue with acpi_ds_auto_serialized_method(). The parser will invoke acpi_ex_release_all_mutexes(), which in return cause mutexes held in ACPI_ERROR_METHOD() failed. Lv Zheng.
