I don't know about the algorithm, rates can repeat, right? So you cannot break
out of the loop here once you found one match?

Are you sure this is correct? You actually check count + 1 rates - from 0
to count inclusively. I think this isn't what you wanted to do, so my
proposal below only checks count rates.

How about this:
for (i = 0; i < num; i++)
if (rate == group->rates[i])
return 0;
if (group->count >= group->max_size) {
group->max_size += 1;
group->rates = krealloc(group->rates,
(sizeof(int) * group->max_size),
GFP_KERNEL);
if (!group->rates)
return -ENOMEM;
}
group->rates[group->count++] = rate;
return 0;

Actually it looks like you should free rates here? I see that not doing this
makes the caller function below easier, but I'd say this is more error-
prone... Up to you but I'd go the "safe" way - if it fails, it frees itself,
if it succeeds - it's freed elsewhere.

I think this will always return 0 here, so you don't need the "ret"
variable in the function scope, you only need it in the "else"
scope above.

Depending whether or not you change the code above, this might change
too.
