Subject: maple_tree: remove repeated sanity checks from mas_wr_append()
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=04d696fe1825d87be02c5160bd85165289bbd711;p=users%2Fjedix%2Flinux-maple.git

maple_tree: remove repeated sanity checks from mas_wr_append()

These sanity checks are now redundant as they are already checked in
mas_wr_store_type(). We can remove them from mas_wr_append().
