Since PTR_ERR_OR_ZERO macro returns zero if input is valid, if some more code gets added in
future after this, then, they might have to change this back to what it is now.
So I ended up continuing with if(IS_ERR(...)) + PTR_ERR towards the end also.
Having said that, I'm fine with this change as well.
