From: Philipp Stanner Date: Mon, 1 Dec 2025 10:50:10 +0000 (+0100) Subject: drm/ttm: Use dma_fence_check_and_signal() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c6c60a2290b335eb5b45c6c7eeb254f18027b3ec;p=thirdparty%2Fkernel%2Flinux.git drm/ttm: Use dma_fence_check_and_signal() The return code of dma_fence_signal() is not useful and shall be removed from the kernel. To do so, the few users who rely on the return code must be ported. Use dma_fence_check_and_signal() and mapp its boolean return code to dma_fence_signal()'s former value for already-signaled fences.
