This clashed badly with commit 6b1ec4789fb1 ("hwmon: (pwm-fan) Add RPM
support via external interrupt"), which added a timer to the pwm-fan
handling.

In particular, that timer now needed the same kind of cleanup changes,
and I'd like you guys (particularly Guenther, who was involved on both
sides) to double-check my merge.

The way I solved it was to just make the pwm_fan_pwm_disable()
callback do both the pwm_diable() _and_ the del_timer_sync() on the
new timer. That seemed to be the simplest solution that meshed with
the new devm cleanup model, but while I build-tested the result, I
obviously did no actual use testing. And maybe there's some reason why
that approach is flawed.

Guenther?
