HI All,

Regarding the above compilation warning reported by bot. I think this is
different than GENMASK.

I am unable to reproduce the compilation warning.

I ran the command:
make W=1 C=1 ARCH=x86_64 CF='-fdiagnostic-prefix -D__CHECK_ENDIAN__' lib/

But the compilation warning didn't show up. Can anyone please point to me
what I am doing wrong here? How shall I reproduce the warning? Thanks !

Regards
Syed Nayyar Waris
