Subject: [PATCH 3/4] ACPICA: iASL table disassembler: Added disassembly support for the NHLT ACPI table
From: Bob Moore <robert.moore@...el.com>
ACPICA commit 94abe858583de24a425b37cb8e62d56c65c4f3cf
Note: support for Vendor-defined microphone arrays and SNR extensions
are not supported at this time -- mostly due to a lack of example tables.
Actual compiler support for NHLT is forthcoming.
