[RFC PATCH 1/3] kernel-doc: better parsing of named variable arguments

[Silvio Fricke <silvio.fricke@xxxxxxxxx>]

Without this patch we get warnings for named variable arguments.

    warning: No description found for parameter '...'
    warning: Excess function parameter 'args' description in 'alloc_ordered_workqueue'
