eb12c95773 drm/radeon: Inline drm_get_pci_dev 
It's the last user, and more importantly, it's the last non-legacy
user of anything in drm_pci.c.

The only tricky bit is the agp initialization. But a close look shows
that radeon does not use the drm_agp midlayer (the main use of that is
drm_bufs for legacy drivers), and instead could use the agp subsystem
directly (like nouveau does already). Hence we can just pull this in
too.

A further step would be to entirely drop the use of drm_device->agp,
but feels like too much churn just for this patch.

cef7663003 drm/omap: Prepare DSS for probing without legacy platform data 
In order to probe display subsystem (DSS) components with ti-sysc
interconnect target module without legacy platform data and using
devicetree, we need to update dss probing a bit.

In the device tree, we will be defining the data also for the interconnect
target modules as DSS really is a private interconnect. There is some
information about that in 4460 TRM in "Figure 10-3. DSS Integration" for
example where it mentions "32-bit interconnect (SLX)".

The changes we need to make are:

1. Parse also device tree subnodes for the compatible property fixup

2. Update the component code to consider device tree subnodes

8c8c06207b drm/ttm: fix leaking fences via ttm_buffer_object_transfer 
Set the drm_device to NULL, so that the newly created buffer object
doesn't appear to use the embedded gem object.

This is necessary, because otherwise no corresponding dma_resv_fini for
the dma_resv_init is called, resulting in a memory leak.

The dma_resv_fini in ttm_bo_release_list is only called if the embedded
gem object is not used, which is determined by checking if the
drm_device is NULL.

b5dacc8fb5 drm/i915: fix header test with GCOV 
$(CC) with $(CFLAGS_GCOV) assumes the output filename with .gcno suffix
appended is writable. This is not the case when the output filename is
/dev/null:

  HDRTEST drivers/gpu/drm/i915/display/intel_frontbuffer.h
/dev/null:1:0: error: cannot open /dev/null.gcno
  HDRTEST drivers/gpu/drm/i915/display/intel_ddi.h
/dev/null:1:0: error: cannot open /dev/null.gcno
make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:

make[5]: *** [../drivers/gpu/drm/i915/Makefile:307:

Filter out $(CFLAGS_GVOC) from the header test $(c_flags) as they don't
make sense here anyway.

2f004792ad drm/omap: venc: Register a drm_bridge 
In order to integrate with a chain of drm_bridge, the internal VENC
encoder has to expose the mode valid, fixup and set, the enable and
disable and the get modes operations through the drm_bridge API.
Register a bridge at initialisation time to do so.

Most of those operations are removed from the omap_dss_device as they
are now called through the drm_bridge API by the DRM atomic helpers. The
only exception is the .get_modes() operation that is still invoked
through the omap_dss_device-based pipeline.

For the time being make the next bridge in the chain optional as the
VENC output is still based on omap_dss_device. The create_connector
argument to the bridge attach function is also ignored for the same
reason. This will be changed later when removing the related
omapdrm-specific display drivers.
