Hi Segher,

Please check below discussion with Greg and Masahiro about

Please check this link, "unused-const-variable" warning is already
disabled for GCC.
Below commit is disabling the "unused-const-variable" for GCC.
commit - c9c6837d39311b0c - "kbuild: move -Wunused-const-variable to
W=1 warning level"

Currently "unused-variable" warnings are disabled for clang and not for
the gcc. Disabling of
"unused-variable" warning also disables "unused-const-variable" warning.
To match same settings
between clang and gcc, disabling "unused-const-variable" warnings for
clang as well.
So with this patch, keeping the same settings for GCC and CLANG with
respect to "unused-const-variable".

-Thanks, Prasad
