+Subject: [PATCH] MDEV-34206 compile failure: fmt use incompatible with
+ libfmt-10.2.[2]+
+
+Upstream libfmt commit https://github.com/fmtlib/fmt/commit/d70729215fba1d54862e407b626abf86ddf409bf
+now requires the format function to be const.
+
+Adjust the function prototype so it is const and can compile.
