I agree.

We use multi-platform defconfig.
I always appreciate the code refactoring
that reduces the object size.

Alexandre Belloni used
https://lore.kernel.org/lkml/9bbcce19c777583815c92ce3c2ff2586@xxxxxxxxxxx/
as a reference, but this is not the output from coccicheck.
The patch author just created a wrong patch by hand.

The deleted semantic patch supports MODE=patch,
which creates a correct patch, and is useful.
