Hi all,

While looking at (dynamic) dma-buf issues and ideas I've spotted a bit
more room for locking down the cross-driver dma_resv rules.

Only functional fallout is a tiny patch for msm, assuming I didn't botch
anything in the auditing of all relevant code.

Comments, review and testing very much appreciated, as usual.

Cheers, Daniel

  drm/modeset: Prime modeset lock vs dma_resv
  dma-resv: Also prime acquire ctx for lockdep
  drm/msm: Don't init ww_mutec acquire ctx before needed
