Christian König c745744a82 dma-buf: fix timeout handling in dma_resv_wait_timeout v2 ... commit 2b95a7db6e upstream. Even the kerneldoc says that with a zero timeout the function should not wait for anything, but still return 1 to indicate that the fences are signaled now. Unfortunately that isn't what was implemented, instead of only returning 1 we also waited for at least one jiffies. Fix that by adjusting the handling to what the function is actually documented to do. v2: improve code readability Reported-by: Marek Olšák <marek.olsak@amd.com> Reported-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Lucas Stach <l.stach@pengutronix.de> Cc: <stable@vger.kernel.org> Link: https://lore.kernel.org/r/20250129105841.1806-1-christian.koenig@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-07-10 16:05:12 +02:00
