ACPICA: DT compiler: prevent error if optional field at the end of table is not present
ACPICA commit a7f73af9003bf4e730db5a133300c01ba7992a01 The data table compiler throws under the following conditions: 1.) there is a table with a last field that is optional 2.) if the optional field is not present 3.) the optional field is the last line of the data table A change was made to dt_compile_table to return an AE_EOF under these conditions. This AE_EOF means that we are at the end of the file. The caller to dt_compile_table() is responsible for handling this case. For DBG2 table, we will complete the compilation of this subtable. For other tables, this could be different.
