Intel compiler support has already been completely removed in commit95207db816("Remove Intel compiler support"). However, it appears that there is still some ICC-related code in scripts/cc-version.sh. There is no harm in leaving the code as it is, but removing the dead code makes the codebase a bit cleaner. Hopefully all ICC-related stuff in the build scripts will be removed after this commit, given the grep output as below: (linux/scripts) $ grep -i -w -R 'icc' cc-version.sh:ICC) cc-version.sh: min_version=$($min_tool_version icc) dtc/include-prefixes/arm64/qcom/sm6350.dtsi:#include <dt-bindings/interconnect/qcom,icc.h> Fixes:95207db816("Remove Intel compiler support") Signed-off-by: Ruihan Li <lrh2000@pku.edu.cn> Reviewed-by: Nick Desaulniers <ndesaulniers@google.com> Reviewed-by: Nathan Chancellor <nathan@kernel.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
