commit c3c1f2d75afc665e26dcc28ca8faa46ab076c4c9 Author: Vladimir Serbinenko phcoder@gmail.com Date: Fri Oct 3 09:39:31 2014 +0200
acpi_add_ssdt_pstates: Remove function.
Nowhere in codebase 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.
