In an eDP application, HPD is not required and on most bridge chips
useless. If HPD is not used, we need to set initial status as connected,
otherwise the connector created by the drm_bridge_connector API remains
in an unknown state.

Use the drm_bridge_connector helper to create a connector for pipelines
that use drm_bridge. This allows splitting connector operations across
multiple bridges when necessary, instead of having the last bridge in
the chain creating the connector and handling all connector operations
internally.

Inside dma-fence-chain, we use a cmpxchg on an RCU-protected pointer. To
avoid the sparse warning for using the RCU pointer directly, we have to
cast away the __rcu annotation. However, we don't need to use void*
everywhere and can stick to the dma_fence*.

The variable err is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.

Why we break out the loops when there are pending bos to be released?
And I just checked the process_one_work. Right after the work item callback is
called, the workqueue itself will call cond_resched. So I think
_
I think it doesn't matter if workitem schedule out. Even we did not schedule
out, the workqueue itself will schedule out later.
So it did not break anything with this patch I think.

This is another example of the usage of cond_sched.

Why we break out the loops when there are pending bos to be released?
We do this anyway if we can't acquire the necessary locks. Freeing
already deleted BOs is just a very lazy background work.
So it did not break anything with this patch I think.
Oh, the patch will certainly work. I'm jus
Including subdirectory Makefile from the driver main Makefile does not
buy us much because this is not real isolation.
Having a single Makefile at the top of the module is clearer, and
it is what this driver almost does.
Move all gvt objects to the i915 main Makefile.

When CONFIG_DRM_I915_GVT=y, the same include path is added twice.
drivers/gpu/drm/i915/Makefile specifies:
subdir-ccflags-y += -I$(srctree)/$(src)
drivers/gpu/drm/i915/gvt/Makefile adds the second '-I $(srctree)/$(src)',
which is redundant.
The include path '-I $(srctree)/$(src)/$(GVT_DIR)/'
