Box" Date: Wed, 26 Apr 2017 16:18:55 +0800 Subject: [PATCH] ACPICA: Disassembler: Do not unconditionally remove temporary names ACPICA commit c46f496df41e53a368f877f88b70bdfc9bd6fdbe Change the Switch disassembly code to check if the conversion can be done before removing temporary (_T_x) names. Prevents invalid disassembly of AML created by older compilers (circa 2005).
