[PATCH v2 0/5] kthread: convert remaining users to kthread_create_worker

[Bradley Morgan <brads@mainlining.org>]

kthread_worker_fn() has carried a FIXME for a decade: it assigns
worker->task = current because the old kthread_run(kthread_worker_fn)
callers never told the worker what task it was. The new
kthread_create_worker*() API sets worker->task before the worker
starts, so the self assignment is dead code.

This series converts the four remaining users of the old pattern
(ivtv, encx24j600, sc16is7xx, cpufreq_schedutil) to the new API,
then removes the self assignment from kthread_worker_fn() while
keeping a WARN_ON() as a sanity check for any out-of-tree users.

v1 -> v2:
- Keep WARN_ON() as a bare sanity check (Frederic, Peter)
- Add comment explaining why the WARN_ON() is there
- Fix subject and changelog wording
