batman 2023.1 fails to compile with implicit func kstrtou64 on debian 5.10.0 - B.A.T.M.A.N - lists.open-mesh.org

      Hi list!
I tried to compile batman-adv-2023.1 for a standard debian bullseye 
kernel 5.10.0-25 but it fails with:
batman-adv/gateway_common.c:55:8: error: implicit declaration of 
function ‘kstrtou64’ [-Werror=implicit-function-declaration]
    55 |  ret = kstrtou64(buff, 10, &lthroughput);
cc1: some warnings being treated as errors
Tried make CFLAGS="-Wno-error=implicit-function-declaration" but that 
doesn't help. Successfully compiled on 5.15.0 (ubuntu LTS).
Any ideas on this?
