ACPICA: iASL: change processing of external op namespace nodes for correctness
ACPICA commit aa866a9b4f24bbec9f158d10325b486d7d12d90f The declaration External (ABCD.EFGH) creates two nodes in the namespace: ABCD and EFGH where ABCD is marked as an implicit external node. ABCD is labeled as implicit because there does not exist a specific External (ABCD) declaration. Before this change, the declaration External (ABCD.EFGH) and External (ABCD.EFGH.IJKL) creates the namespace nodes ABCD, EFGH, and IJKL where ABCD and EFGH are labeled as implicit external nodes. This is incorrect. The only implicit node should be ABCD because EFGH and IJKL are explicit nodes. This change fixes the labeling procecess of external op namespace nodes so that nodes are properly labeled as implicit external. Due to this commit, the below ASL code results in a compilation error. definition_block ("DSDT.aml", "DSDT", 0x02, "INTEL", "BDW ", 0x0) { External(\_SB.PCI0.GFX0, device_obj) External(\_SB.PCI0.GFX0.ALSI) Scope(\_SB) { Device(PCI0) { Device(GFX0) { Name(_ADR, 0x00020000) } } } } Link: https://github.com/acpica/acpica/commit/aa866a9b Signed-off-by: Erik Schmauss <erik.schmauss@intel.com> Signed-off-by: Bob Moore <robert.moore@intel.com> Signed-off-by: Rafael J.
