4 | Subject: [PATCH 33/65] Revert "drm/i915/bios: Reverse order of 100/120 Mhz SSC clocks" | ||
5 | |||
6 | As I feared, whilst this fixed the clocks for the Lenovo U160, it broke | ||
7 | many other machines. So lets reverts commit 448f53a1ede54eb854d036abf | ||
8 | and search for the real bug. | ||
