[RESEND PATCH 0/5] kthread: remove worker->task self-assignment

[Bradley Morgan]

From: Bradley Morgan <brads@xxxxxxxxxxxxxx>

Resent as a proper series with cover letter. The first send went out as
five separate threads instead of one.

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 even
starts, so the self-assignment is dead code.

Four drivers were still on the old API. Convert them, then remove the
FIXME.

No functional change intended.

Bradley Morgan (5):
  media: ivtv: convert to kthread_run_worker
  net: encx24j600: convert to kthread_run_worker
  tty: sc16is7xx: convert to kthread_run_worker
  cpufreq: schedutil: convert to kthread_create_worker
  kthread: remove worker->task self-assignment
