Re: [PATCH] remoteproc: fix kernel-doc warnings

[Randy Dunlap]

Hi,

kernel-doc supports "..." as a function argument for varargs.
See Documentation/doc-guide/kernel-doc.rst:

"If a function has a variable number of arguments, its description should
be written in kernel-doc notation as::

      * @...: description"


So the below could be done as:

 * @name: carveout name to find

although I'm not so sure about the descriptions there.
