The htmldocs step failed on its own success criterion. The only diagnostic
in the log was
WARNING: dot(1) not found, for better output quality install graphviz
which says nothing about this patch. Failing the job on any occurrence of
"warning" anywhere in a kernel documentation build is too blunt: that build
emits diagnostics that depend on what happens to be installed on the runner.
Install graphviz so the warning is gone for the right reason, and narrow the
check to diagnostics that actually name i2c-imc-skylake, which is what the
step was meant to verify.
