[PATCH 2/6] amd/amdkfd: Ignore return code of dma_fence_signal()

[Philipp Stanner <phasta@kernel.org>]

The return code of dma_fence_signal() is not really useful as there is
nothing reasonable to do if a fence was already signaled. That return
code shall be removed from the kernel.

Ignore dma_fence_signal()'s return code.
