Hello,
while working on the pwm core I noticed that pwm-crc doesn't assign .owner in its pwm_ops structure. This isn't a problem in practise though as this driver can only be compiled built-in (up to now).
Still prevent future pwm drivers not assigning .owner by wrapping pwmchip_add() in a macro that automates owner handling simplifying each driver a (tiny) bit.
I also found that there is no hard reason to only compile pwm-crc as a built-in on x86, so this limitation is lifted in the second patch.
Best regards Uwe

base-commit: 3ccb179aa40d931eb00ef8910d7b812a95659563
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.

Hi Uwe,
Thank you for the patch.

While technically speaking the ops and pwm chip could be provided by different modules, such a use case would likely require a high level of self-inflicted pain, so I think the change is fine.

Missing documentation for the new owner parameter.

Missing documentation update here too, for both pwm_ops and pwm_chip.
