Box" ACPICA commit 0f6cc80e8af519a3c31184367b0a9be7a399cf53 iasl compiles Switch/Case statements into a single iteration While loop with If/Else statements. This patch adds support to recognize this generated compiler output and disassemble it back to the original Switch statement. Linux kernel is not affected by this patch.
