Some of the WA applied using WA batch buffers perform writes to scratch page.
In the current flow WA are initialized before scratch obj is allocated.
This patch reorders intel_init_pipe_control() to have a valid scratch obj
before we initialize WA.

You could squash the last several lines down to just:
return logical_ring_init(dev, ring);
.Dave.
yes but this is updated based on suggestion from Chris to allocate
wa_ctx page during ring init itself; in the updated version it is not
possible as we need to free that page also if ring_init fails.
I sent the updated patches in the same series so as to collate all
reviews instead of resending as a separate series.
