The quilt patch titled
     Subject: maple_tree: cleanup function descriptions
has been removed from the -mm tree.  Its filename was
     maple_tree-cleanup-function-descriptions.patch

This patch was dropped because it was merged into the mm-stable branch
of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm

Subject: maple_tree: cleanup function descriptions
Date: Fri, 30 Aug 2024 22:04:00 +0000

This patch tries to cleanup some function description:

  * function name mismatch
  * parameter name mismatch
  * parameter all end up with ':'
  * not prefix '*' if parameter is a pointer

There is still some missing description of parameters, I didn't add them
since I am not sure the exact meaning.
