+Fix the dead code error as follows:

+ Compiling coverage-dump v0.1.0 (/home/poky/build-st/tmp/work/core2-64-poky-linux/rust/1.77.0/rustc-1.77.0-src/src/tools/coverage-dump)

+ 222 | Expansion(u32),
+ | --------- ^^^
+ | |
+ | field in this variant
+ |
+ = note: `-D dead-code` implied by `-D warnings`
+ = help: to override `-D warnings` add `#[allow(dead_code)]`
+ help: consider changing the field to be of unit type to suppress this warning while preserving the field numbering, or remove the field

+ 222 | Expansion(()),

+
+ error: could not compile `coverage-dump` (bin "coverage-dump") due to 1 previous error
+
+Only the required change is backported here to run the build without any errors.
+Other changes are merged with the commit in v1.78.
