[PATCH] docs: xforms_lists: allow __maybe_unused in func parameters

[Randy Dunlap]

Bart has a patch (not yet merged) that causes kernel-doc warnings:

WARNING: ./include/linux/highmem.h:235 function parameter '__maybe_unused' not described in 'clear_user_pages'
Documentation/mm/highmem:211: ./include/linux/highmem.h:222: WARNING: Error in declarator or parameters

Handle this by adding "__maybe_unused" to the list of known function
parameter modifiers.
