There are many kernel developers who use sparse to verify the
correctness of endianness annotations (__be32, __le32, ...). When
compiling kernel code with sparse every warning that is reported by
sparse should be analyzed. Most kernel developers consider it annoying
having to deal with false positive warnings. So I think that is useful
to suppress false positive sparse warnings if it is possible to
suppress false positives with a reasonable effort.

Thanks,

Fubo.
