[PATCH 1/4] cpufreq: Add a cpufreq driver for Marvell Dove

No.

Take a look at request_threaded_irq(). It contains:

1421         if (!handler) {
1422                 if (!thread_fn)
1423                         return -EINVAL;

So devm_request_irq() will fail, and so the probe function will fail.
