Changelog:
v2: Rebased the patchset on top of drm-next rather than Linus' latest -rc

A few drivers in drivers/gpu/drm are component-enabled and use quite similar
code sequences to probe for their encoder slaves at the remote end of the ports.
Move the code into a "generic" function and remove it from the drivers.

The end results is that drivers get a reference count fix (imx), more thorough
error checking (imx again), setting the DMA coherent mask (armada) plus a 
decrease
in the overall count of LoC.

I'm looking for comments and testing of the patchset (only compile tested from 
my
end as I don't have access to all the devices touched by the changes). My main
interest is in finding out if -EINVAL is the correct code to return if
dev->of_node == NULL (handy now, as it is different from the other possible 
error
codes and used in armada to trigger old platform_data support. Also looking for
thoughts on the correctness of the patch and if it possible to co-opt more 
drivers
into using the function.

Best regards,
Liviu
