[PATCH 40/42] ACPICA: Add "root node" case to the ACPI name repair code

Show all headers | View raw

From: Bob Moore <robert.moore@intel.com>

ACPICA commit 95b40b31aa8148629fbe5de0356725fc01298003

Special-case the namespace root node, it has an unusual name.
This case can occur if there are errors during the execution
of module-level code.
