From 1b7199fe9840737397d335922033aa2c3cca92c6 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 23 Jul 2014 12:29:56 +0200 Subject: drm: move module initialization to drm_stub.c Most of the new DRM management functions are nowadays in drm_stub.c. By moving the core module initialization to drm_stub.c we can make several global variables static and keep the stub-open helper local. The core files now look like this: drm_stub.c: Core management drm_drv.c: Ioctl dispatcher drm_ioctl.c: Actual ioctl backends drm_fops.c: Char-dev file-operations A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.
