Merge branch 'msm-fixes-4.13-rc3' of git://people.freedesktop.org/~robclark/linux into drm-fixes

Bunch of msm fixes for 4.13

* 'msm-fixes-4.13-rc3' of git://people.freedesktop.org/~robclark/linux:
  drm/msm: gpu: don't abuse dma_alloc for non-DMA allocations
  drm/msm: gpu: call qcom_mdt interfaces only for ARCH_QCOM
  drm/msm/adreno: Prevent unclocked access when retrieving timestamps
  drm/msm: Remove __user from __u64 data types
  drm/msm: args->fence should be args->flags
  drm/msm: Turn off hardware clock gating before reading A5XX registers
  drm/msm: Allow hardware clock gating to be toggled
  drm/msm: Remove some potentially blocked register ranges
  drm/msm/mdp5: Drop clock names with "_clk" suffix
  drm/msm/mdp5: Fix typo in encoder_enable path
  drm/msm: NULL pointer dereference in drivers/gpu/drm/msm/msm_gem_vma.c
  drm/msm: fix WARN_ON in add_vma() with no iommu
  drm/msm/dsi: Calculate link clock rates with updated dsi->lanes
  drm/msm/mdp5: fix unclocked register access in _cursor_set()
  drm/msm: unlock on error in msm_gem_get_iova()
  drm/msm: fix an integer overflow test
  drm/msm/mdp5: Fix compilation warnings
