In kernel-doc comments, unary operator * collides with Sphinx/ docutil's markdown for emphasizing. This resulted in additional warnings from "make htmldocs": WARNING: Inline emphasis start-string without end-string. , as reported recently [1]. Those have been worked around either by escaping * (like \*param) or by using inline-literal form of ``*param``, both of which are specific to Sphinx/docutils. Such workarounds are against the kenrel-doc's ideal and should better be avoided. Instead, add "*" to the list of unary operators kernel-doc recognizes and make the form of *@param available in kernel-doc comments.
