Hi,

I don't see this on v5.4-rc1 with defconfig or allyesconfig and
sparse's current version. Any sparse's version since roughly
mid-December should give the same result.

If you're using an older version of sparse, please upgrade.
Otherwise, please send me your config so that I can take a look at it.


Best regards,
