Can the Hulk check that verifies where PTR_ERR_OR_ZERO() can be
introduced be deactivated? I think this patch makes the code less
readable instead of making it more readable.
Thanks,
Bart.

Is this a useful change? My personal opinion is that the current
implementation (without this patch) is easier to read.
Thanks,
Bart.

PTR_ERR_OR_ZERO contains if(IS_ERR(...)) + PTR_ERR, just use
PTR_ERR_OR_ZERO directly.
