Subject: maple_tree: Clean up mas_dfs_postorder()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d83434d6cb532aac0afcf00c86e91966fd6fe0e4;p=users%2Fjedix%2Flinux-maple.git

maple_tree: Clean up mas_dfs_postorder()

Convert loop type to ensure all variables are set to make the compiler
happy, and use the mas_is_none() function instead of explicitly checking
the node in the maple state.
