[PATCH v2 1/2] pwm: Manage owner assignment implicitly for drivers

Uwe Kleine-König
2023-08-04T14:30:20Z

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.
