While looking into further feedback, I noticed I did the same mistake in
all the patches that convert the drivers to use this function. I did

	git filter-branch --msg-filter 'sed "s/Make use of pwmchip_parent() macro/Make use of pwmchip_parent() accessor/; s/commit as struct pwm_chip::dev, use the macro/commit as struct pwm_chip::dev, use the accessor/; s/provided for exactly this purpose./function provided for exactly this purpose./"' linus/master..

on my branch to make the typical commit log read:

	pwm: atmel: Make use of pwmchip_parent() accessor
	
	struct pwm_chip::dev is about to change. To not have to touch this
	driver in the same commit as struct pwm_chip::dev, use the accessor
	function provided for exactly this purpose.

I wont resend the whole series if this is the only change to it.

Best regards
Uwe
