drm/udl: properly check for error pointers

2014-11-26T00:03:18Z

The drm_prime_pages_to_sg() function never returns NULL pointers, only error pointers and valid pointers. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: handle page mapping in dmabuf export.

2014-11-26T00:03:00Z

Fixes dmabuf export failure with -E_NOMEM when the page is not mapped. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

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

2014-11-21T02:16:35Z

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. Signed-off-by: Markus Elfring Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

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

2014-11-20T01:41:37Z

Only importing an FD to a handle is currently supported on UDL, but the exporting functionality is equally useful. Signed-off-by: Haixia Shi Reviewed-by: Stéphane Marchesin Signed-off-by: Dave Airlie

drm/udl: add cache flags definitions for udl_gem_object

2014-11-20T01:41:32Z

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

2014-11-04T23:14:55Z

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

2014-09-10T07:43:27Z

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. Signed-off-by: David Herrmann Reviewed-by: Thierry Reding Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: add driver->set_busid() callback

2014-09-10T07:43:04Z

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.
