Message-ID: <20231006135032.3328523-1-kuba@kernel.org> Date: Fri, 6 Oct 2023 06:50:32 -0700 From: Jakub Kicinski <kuba@...nel.org> To: davem@...emloft.net Cc: netdev@...r.kernel.org, edumazet@...gle.com, pabeni@...hat.com, Jakub Kicinski <kuba@...nel.org>, Lorenzo Bianconi <lorenzo.bianconi@...hat.com> Subject: [PATCH net-next] tools: ynl-gen: handle do ops with no input attrs The code supports dumps with no input attributes currently thru a combination of special-casing and luck. Clean up the handling of ops with no inputs. Create empty Structs, and skip printing of empty types. This makes dos with no inputs work.
