From b752e4f402b2a96d1b9545b5fed3df09d2990743 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Fri, 3 Oct 2014 09:39:31 +0200 Subject: acpi_add_ssdt_pstates: Remove function. Nowhere in database p_state_num is set. So this whole function ends up being a noop. Moreover the offsets used by it are wrong with any optimizing iasl. Remove it in preparation of move to per-device ACPI.
