[PATCH] drm/i915: Pass ww ctx to pin_map, v2.

24 Mar 2021

This will allow us to explicitly pass the ww to pin_pages,
when it starts taking it.
This allows us to finally kill off the explicit passing of ww
by retrieving it from the obj.
Changes since v1:
- Rename 'ret' to ptr, fix error handling of return ptr.
