ACPICA: iASL compiler: allow compilation of externals with paths that refer to existing names
ACPICA commit 9a252114197409290813bee570e9d53c22b99d32
This change allows compilation of code like the following:
definition_block (...)
{
External (ABCD.EFGH)
Device (ABCD)
{
Name (IJLK,0)
}
}
but does not allow compilation of code like the following:
definition_block (...)
{
External (ABCD)
Device (ABCD)
{
Name (EFGH,0)
}
}
