Hi Dave,
After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:
drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:818:6: error: redefinition of
'amdgpu_ttm_tt_affect_userptr'
bool amdgpu_ttm_tt_affect_userptr(struct ttm_tt *ttm, unsigned long start,
^
drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:799:6: note: previous definition of
'amdgpu_ttm_tt_affect_userptr' was here
bool amdgpu_ttm_tt_affect_userptr(struct ttm_tt *ttm, unsigned long start,
^
Caused by a bad git resolution in commit
971f3e7dd355 ("Merge remote-tracking branch 'drm/drm-next'")
I have added the following as a merge fix up patch and can carry it
as necessary.
