[Nouveau] [RESEND 00/15] Rid W=1 warnings from GPU

This set is part of a larger effort attempting to clean-up W=1
kernel builds, which are currently overwhelmingly riddled with
niggly little warnings.

Lee Jones (15):
  drm/xlnx/zynqmp_disp: Use correct kerneldoc formatting in zynqmp_disp
  drm/xlnx/zynqmp_dp: Fix function name zynqmp_dp_link_train() ->
    zynqmp_dp_train()
  drm/vkms/vkms_composer: Fix a few different kerneldoc formatting
  drm/mediatek/mtk_disp_aal: Remove half completed incorrect struct
    header
  drm/mediatek/mtk_disp_ccorr: Remove half completed incorrect struct
    header
  drm/nouveau/nvkm/subdev/acr/lsfw: Remove unused variable 'loc'
  drm/nouveau/nvkm/subdev/bios/init: Demote a bunch of kernel-doc abuses
  drm/nouveau/nvkm/subdev/volt/gk20a: Demote kerneldoc abuses
  drm/nouveau/nvkm/engine/gr/gf100: Demote kerneldoc abuse
  drm/nouveau/nvkm/engine/gr/tu102: Staticify local function
    gf100_fifo_nonstall_block()
  drm/amd/display/amdgpu_dm/amdgpu_dm_helpers: Move SYNAPTICS_DEVICE_ID
    into CONFIG_DRM_AMD_DC_DCN ifdef
  drm/nouveau/dispnv04/crtc: Demote kerneldoc abuses
  drm/nouveau/nvkm/engine/gr/tu102: Completely remove unused function
    ?tu102_gr_load?
  drm/radeon/radeon_ttm: Remove unused variable 'rbo' from
    radeon_bo_move()
  drm/amd/amdgpu/sdma_v6_0: Demote a bunch of half-completed function
    headers
