From 7e0e41963740525af702bb23edede8ae9afc4ac0 Mon Sep 17 00:00:00 2001 From: Kleber Sacilotto de Souza Date: Fri, 3 May 2013 19:43:13 -0300 Subject: radeon: use max_bus_speed to activate gen2 speeds radeon currently uses a drm function to get the speed capabilities for the bus, drm_pcie_get_speed_cap_mask. However, this is a non-standard method of performing this detection and this patch changes it to use the max_bus_speed attribute.
