Checked it on the git source, it was moved from default
to the -Wsizeof-bool flag with commit: 2667c2d4ab3342b54283d16f1d62e6d715f3b373.
That's why I got the warning and you didn't. If you turn on this flag,
you'll get it. It's not really anything important, I'm doing a patch for the
eudyptula-challange, if you don't accept it, I'll find sth else in
drivers/staging.

Why send this twice?

And again, I don't think this is fixing anything, what is wrong with
this code?

confused,

Your From: email line and signed-off-by: line names do not match, so I
can't take this patch :(

Please fix up and resend.

What is this fixing?  Why can't we have a bool as a per-cpu variable?
We are only writing true or false to it.
