Personally I prefer the current style because it's more consistent with all
the other calls in the same function (return ret when ret != 0).
It also allows you to easily add/remove calls without having to deal with
the last special case return my_last_fun_call(...).
Anyway it's not a big deal, I think it's your call.
I agree. I also prefer the current style for these reasons. The compiler will
also generate the same code in both cases.
I don't think it really simplifies the code.
But if you really insist on doing this change, go for it. You get my ack for
fc0011
I am also against that kind of simplifications. Even it reduces line or
two, it makes code more inconsistent, which means you have to make extra
thinking when reading that code. I prefer similar repeating patterns as
much as possible.
This is how I do it usually, even there is that extra last goto.
ret = write_reg();
if (ret)
goto err;
ret = write_reg();
if (ret)
goto err;
err:
return ret;
};
