Merge tag 'drm-fixes-2026-03-14' of https://gitlab.freedesktop.org/drm/kernel 

Pull drm fixes from Dave Airlie:
 "The weekly drm fixes. This is mostly msm fixes across the functions,
  with amdgpu and i915. It also has a core rust fix and changes in
  nova-core to take advantage of it, and otherwise just has some minor
  driver fixes, and marks loongsoon as orphaned.

  rust:
   - Fix safety issue in dma_read! and dma_write!

  nova-core:
   - Fix UB in DmaGspMem pointer accessors
   - Fix stack overflow in GSP memory allocation

  loongsoon:
   - mark drm driver as unmaintained

  msm:
   - Core:
      - Adjusted msm_iommu_pagetable_prealloc_allocate() allocation type
   - DPU:
      - Fixed blue screens on Hamoa laptops by reverting the LM
        reservation
      - Fixed the size of the LM block on several platforms
      - Dropped usage of %pK (again)
      - Fixed smatch warning on SSPP v13+ code
      - Fixed INTF_6 interrupts on Lemans
   - DSI:
      - Fixed DSI PHY revision on Kaanapali
      - Fixed pixel clock calculation for the bonded DSI mode panels
        with compression enabled
   - DT bindings:
      - Fixed DisplayPort description on Glymur
      - Fixed model name in SM8750 MDSS schema
   - GPU:
      - Added MODULE_DEVICE_TABLE to the GPU driver
      - Fix bogus protect error on X2-85
      - Fix dma_free_attrs() buffer size
      - Gen8 UBWC fix for Glymur

  i915:
   - Avoid hang when configuring VRR [icl]
   - Fix sg_table overflow with >4GB folios
   - Fix PSR Selective Update handling
   - Fix eDP ALPM read-out sequence

  amdgpu:
   - SMU13 fix
   - SMU14 fix
   - Fixes for bringup hw testing
   - Kerneldoc fix
   - GC12 idle power fix for compute workloads
   - DCCG fixes

  amdkfd:
   - Fix missing BO unreserve in an error path

  ivpu:
   - drop unnecessary bootparams register setting

  amdxdna:
   - fix runtime/suspend resume deadlock

  bridge:
   - ti-sn65dsi83: fix DSI rounding and dual LVDS

  gud:
   - fix NULL crtc dereference on display disable"
