iio: frequency: adf4350: using an uninitialized variable
GCC complains that we use an uninitialized variable if the user passes
an invalid parameter to adf4350_read(). I decided that we should return
-EINVAL instead in that case.
However, when I looked up at adf4350_write() it returned -ENODEV for
that condition. In the end, I decided the -EINVAL was the right thing
and I change adf4350_write() to match.
