error pointers and valid pointers.

drm/udl: Deletion of an unnecessary check before the function call "vunmap"

2014-11-21T02:16:35+00:00

The vunmap() function performes also input parameter validation. Thus the test
around the call is not needed.

This issue was detected by using the Coccinelle software.

drm/udl: add support to export a handle to a FD on UDL.

2014-11-20T01:41:37+00:00

Only importing an FD to a handle is currently supported on UDL,
but the exporting functionality is equally useful.

drm/udl: add cache flags definitions for udl_gem_object

2014-11-20T01:41:32+00:00

By default set udl_gem_object as cacheable, but set WC flag when attaching
dmabuf. In udl_gem_mmap() update cache attributes based on the flags, similar
to exynos_drm_gem_mmap().

drm: Move drm_crtc_init from drm_crtc.h to drm_plane_helper.h

2014-11-04T23:14:55+00:00

Just a bit of OCD cleanup on headers - this function isn't the core
interface any more but just a helper for drivers who haven't yet
transitioned to universal planes. Put the declaration at the right
spot and sprinkle necessary #includes over all drivers.

Maybe this helps to encourage driver maintainers to do the switch.

v2: Fix #include ordering for tegra, reported by 0-day builder.

v3: Include required headers, reported by Thierry.

drm: merge drm_usb into udl

2014-09-10T07:43:27+00:00

This merges all the remains of drm_usb into its only user, udl. We can
then drop all the drm_usb stuff, including dev->usbdev.

drm: add driver->set_busid() callback

2014-09-10T07:43:04+00:00

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.
