From 935f3877331b4a8bf429cb81f488ea39ea896325 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Tue, 29 Dec 2015 13:55:05 +0800 Subject: [PATCH] ACPICA: iasl/acpiexec: Update input file handling and verification ACPICA commit 3a6f2a516dd35a4daacbc5b5144d1db763ff2cb0 Improve and cleanup verification of ACPI tables within input files. Share more code between the disassembler and acpiexec. This patch only affects application debugger commands, thus it is a no-op chage for Linux kernel.
