From 1c8887dd01d97781471c9a876e3a4e804bb33f31 Mon Sep 17 00:00:00 2001 From: David Herrmann Date: Wed, 2 Oct 2013 11:23:36 +0200 Subject: [PATCH] drm: move drm_lastclose() to drm_fops.c Try to keep all functions that handle DRM file_operations in drm_fops.c so internal helpers can be marked static later. This makes the split between the 3 core files more obvious: - drm_stub.c: DRM device allocation/destruction and management - drm_fops.c: DRM file_operations (except for ioctl) - drm_drv.c: Global DRM init + ioctl handling Well, ioctl handling is still spread throughout hundreds of source files, but at least the others are clearly defined this way.
