------------------------------------------------------ From: Arnd Bergmann arnd@arndb.de Subject: radix tree: remove unused variable Date: Fri, 11 Aug 2023 15:10:13 +0200
Recent versions of clang warn about an unused variable, though older versions saw the 'slot++' as a use and did not warn:
radix-tree.c:1136:50: error: parameter 'slot' set but not used [-Werror,-Wunused-but-set-parameter]
It's clearly not needed any more, so just remove it.
