Hi Michael,

That's odd. I don't get any CHECK messages if I run exactly the same
command as above:

$ pwd
/home/sevinj/k/staging/drivers/staging/r8188eu/core
$ ~/k/staging/scripts/checkpatch.pl -f rtw_mlme.c | grep 'CHECK:' | wc -l
0

I have to specify --strict to get CHECK messages:

$ ~/k/staging/scripts/checkpatch.pl --strict -f rtw_mlme.c | grep
'CHECK:' | wc -l
167

I don't know why that is. I'm on Ubuntu 20.04 and it looks like I'm
running checkpatch version 0.32:

$ ~/k/staging/scripts/checkpatch.pl -h
Usage: /home/sevinj/k/staging/scripts/checkpatch.pl [OPTION]... [FILE]...
Version: 0.32
