[PATCH 0/6] dma-fence: Remove return code of dma_fence_signal() et al.

[Philipp Stanner <phasta@kernel.org>]

Barely anyone uses dma_fence_signal()'s (and similar functions') return
code. Checking it is pretty much useless anyways, because what are you
going to do if a fence was already signal it? Unsignal it and signal it
again? ;p

Removing the return code simplifies the API and makes it easier for me
to sit on top with Rust DmaFence.

Philipp Stanner (6):
  dma-buf/dma-fence: Add dma_fence_test_signaled_flag()
  amd/amdkfd: Ignore return code of dma_fence_signal()
  drm/gpu/xe: Ignore dma_fenc_signal() return code
  dma-buf: Don't misuse dma_fence_signal()
  drm/ttm: Remove return check of dma_fence_signal()
  dma-buf/dma-fence: Remove return code of signaling-functions
