X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1538ac64f532431a40e2f6c528f1ee108d5fa431;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ACPICA: Tables: Merge DMAR table structure updates

This patch is a back port result of the following Linux commit:
  Author: David Woodhouse <David.Woodhouse@intel.com>
  Subject: iommu/vt-d: Add ACPI namespace device reporting structures

ACPICA need to handle old compilers where u8 object_name[] is only allowed
for an initialized variable. This patch reduces back port source code
differences between Linux and ACPICA upstream.
