X-Git-Tag: firefly_0821_release~176^2~2728^2~7^2~7 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=4dcd78d80d37a360f5faab422a4e48b2cfd4abe4;p=firefly-linux-kernel-4.4.55.git ACPICA: iASL: Add support for to_PLD macro. This macro is intended to simplify the constuction of _PLD buffers. NOTE: Prototype only, subject to change before this macro is added to the ACPI specification. David E. Box. Signed-off-by: David E.
