Patch 1 removes unreachable error handling in amdgpu_fence_emit(). dma_fence_wait(old, false) is not interruptible and cannot return an error, so the existing check is dead code.
Patch 2 builds on this by making amdgpu_vm_flush() non-failing in the job submission path. The function is converted to return void, and the caller no longer handles an error return. This reflects the fact that failures are not expected in this path.
