[RFC Patch 04/19] ACPI: Let the parser return false for disabled resources
From: Jiang Liu
Date: Wed Jan 07 2015 - 21:30:42 EST
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
If the parser disables a resource during parsing, let it return false,
so the calling code does not need to implement further checks.
