Sparse warnings from calls to max3() and max

Sparse warnings from calls to max3() and max

[Larry Finger]

Hi,

Sparse has suddenly started issuing as many as 11 warnings of "expression using 
sizeof(void)" for each call to max3(). There are similar warnings for calls to 
max(), thus I think this is the origin of the problem. My sparse version is 
20180324-1.3-x86_64 installed in openSUSE Tumbleweed. My kernel is 4.19.0-rc6.

Thanks,

Larry

Hi,

This problem is resolved in a more recent version of sparse,
the one you can find at:
  git://github.com/lucvoo/sparse-dev

See Linus' email about it:
  https://lore.kernel.org/lkml/CA+55aFzYEnZR2GZLR-DwpONjMNYGYoDy+6AWLCVNayWiaZuqoA@mail.gmail.com/T/#u

NB. The official version hosted on kernel.org is not uptodate but
    I hope this will solved in a few weeks.

Best regards,

Thanks. I'll ignore those warnings for now.
