Return statements in functions returning bool should use
true/false instead of 1/0.

Per 2b076054e524 ("remove boolinit.cocci"), I have a very dim view of

Hi Peterz,

Sorry for the noise, we'll disable the check.

The bot is stupid, it used the commit that first found the issues,
we'll take a look at it.

Best Regards,
