Hi,

> Instead of requiring each driver to care for assigning the owner member
> of struct pwm_ops, handle that implicitly using a macro. Note that the
> owner member has to be moved to struct pwm_chip, as the ops structure
> usually lives in read-only memory and so cannot be modified.
> 
> The upside is that new lowlevel drivers cannot forget the assignment 
> and
> save one line each. The pwm-crc driver didn't assign .owner, that's not
> a problem in practise though as the driver cannot be compiled as a
> module.
