platform/x86: lg-laptop: Add support for the HDAP opregion field
Various LG notebooks have a special field called "HDAP" inside
the ACPI operation region handled by the lg-laptop driver:
Field (XIN1, AnyAcc, Lock, Preserve)
{
DMSG, 8,
HDAP, 8,
Offset (0x10),
P80B, 8,
P81B, 8,
P82B, 8,
P83B, 8,
P84B, 8,
P85B, 8,
P86B, 8,
P87B, 8,
Offset (0x3E8),
PMSG, 1600
}
This field is set to 1/0 when the HD audio device is enabled/disabled
using the _PS0/_PS3 ACPI control methods. Add support for this field
to avoid printing warning messages when AML bytecode writes data
into it.
