Hello,

some time ago the pwm core implemented additional locking to protect
lowlevel driver callbacks against driver removal. A side effect is that
.apply() and .get_state() are serialized. This allows to drop some
locking that is now superfluous due to the core's locking.

I identified a few drivers that are affected; these are cleaned up
accordingly here.
I applied these patches to
https://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux.git pwm/for-next
now.

Best regards
Uwe
