FROMGIT: iio: hrtimer-trigger: Fix potential integer overflow in iio_hrtimer_store_sampling_frequency
Add suffix ULL to constant 1000 in order to avoid a potential integer
overflow and give the compiler complete information about the proper
arithmetic to use. Notice that this constant is being used in a context
that expects an expression of type unsigned long long, but it's
currently evaluated using 32-bit arithmetic.
Addresses-Coverity-ID: 1503062 ("Unintentional integer overflow")
Fixes: dafcf4ed8392 ("iio: hrtimer: Allow sub Hz granularity")
