In a different thread on the pwm mailing list I suggested to add

	pwm: bcm-iproc: prevent unloading the driver module while in use

to this pull request. You didn't comment and didn't add it. :-|
(https://patchwork.ozlabs.org/patch/1178972/)

While this is not a recent regression (it was introduced in 4.8-rc1) I
think it's still worth to be fixed, don't you agree?
 
Best regards
Uwe
