The 'irq' member of the vdoa_data struct is only used inside probe,
so there is no need for it. Use a local variable 'ret' instead.

platform_get_resource() may fail and in this case a NULL dereference
will occur.
Prevent this from happening by returning an error on
platform_get_resource() failure.

As long as only one CODA context is running we get alternating device_run()
and wait_for_completion() calls, but when more then one CODA context is
active, other VDOA slots can be inserted between those calls for one context.
Make sure to wait on job completion before running a different context and
before destroying the currently active context.

The device driver platform is actually written to during registration,
for setting the owner field, so platform_driver_register() does not
take a const pointer:

Remove the modifier again.

Despite checkpatch comments, it seems that ARM doesn't like
to use constified structs.

So, let's just remove it.
This reverts commit 126f52b02e6ec6a25f0b32058a91648304922d4a.

The i.MX6 Video Data Order Adapter's (VDOA) sole purpose is to convert
from a custom macroblock tiled format produced by the CODA960 decoder
into linear formats that can be used for scanout.
