The following build errors are noticed on riscv with clang-18 toolchain
but gcc-12 builds pass.

However, compared with older releases this is a build regression on
stable-rc 5.10.

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

riscv:
 defconfig - gcc-12 - PASS
 defconfig - clang-18 - FAILED

Build error:
