Quick 4.15 misc pull for the build fix:

Cross-subsystem Changes:
- piles an piles of misc/trivial patches all over, some more from
  outreachy applicants

Core Changes:
- build fix for the bridge/of cleanup (Maarten)

- some kerneldoc typo fixes from Thierry

Driver Changes:
- vc4: Fix T-format tiling scanout, cleanup clock divider w/a (Anholt)
- sun4i: small cleanups and improved code comments all over (Chen-Yu
  Tsai)
