In olden times there was just strict_strtol() and strict_strtoul().
These days we have kstrtou8() and kstrtoint() and a bunch of others.
So when you do these patches you have to take more time to consider
what type we should be using and update the surrounding code.
I haven't reviewed all of these so please check everything again.

This bug is in the original code as well. "val" is long but it
should be unsigned long. Later we check that:
if (val > AD5933_MAX_OUTPUT_FREQ_Hz) {
Forgetting that "val" could be a negative number.

For these we should be using the new kstrtou8() functions.

Same.

For this one we should make "val" an int.
