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.
v3: (Tvrtko)
- Replaced mutex_lock with mutex_lock_interruptible_nested() in
the i915 patch.
v4: (Tvrtko)
- Dropped the patch added in v2 as it was deemed unnecessary.
v5: (Tvrtko)
- Fixed yet another typo in the drm core patch: should have
passed caller_mode instead of mode to the iterator.
