The first patch is a drm core patch that replaces the for loop in
drm_mm_insert_node_in_range() with the iterator and would not
cause any functional changes. The second patch is a i915 driver
specific patch that also uses the iterator but solves a different
problem.
v2:
- Added a new patch to this series to fix a potential NULL
dereference.
- Fixed a typo associated with the iterator introduced in the
drm core patch.
- Added locking around the snippet in the i915 patch that
traverses the GGTT hole nodes.
