Subject: tools: ynl-gen: handle do ops with no input attrs
Patch-mainline: v6.7-rc1
Git-commit: 8cea95b0bd7930367f11e2abceda6e096dd18943
References: jsc#PED-3311
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.
