NAK.

Below patch works properly on my side, no Sphinx errors and proper HTML
view, while still keeping proper-alignment in the C code.

Sorry, you're too focusing on the HTML side.

Making the C code readable, not just the HTML output, is quite
important.

From: Bagas Sanjaya <bagasdotme@xxxxxxxxx>

Use bullet-list RST syntax for kernel-doc parameters' flags and
interrupt mode descriptions. Otherwise Sphinx produces "Unexpected
identation" errors and warnings.
