From 915b4d11b8b9e7b84ba4a4645b6cc7fbc0c071cf Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Fri, 29 Aug 2014 12:12:43 +0200 Subject: drm: add driver->set_busid() callback One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe). Therefore, we create two different drivers for each platform during module_init() and set the set_busid() callback respectively.
