Following MIPS builds failed on 6.6.y and 6.1.y
but passed 6.7.y and Linux-next and mainline builds.

mips:

  * build/clang-17-defconfig
  * build/clang-nightly-defconfig
  * build/gcc-12-allmodconfig
  * build/gcc-12-cavium_octeon_defconfig
  * build/gcc-12-defconfig
  * build/gcc-12-malta_defconfig
  * build/gcc-8-allmodconfig
  * build/gcc-8-cavium_octeon_defconfig
  * build/gcc-8-defconfig
