[greybus-dev] Re: [PATCH v2 1/2] pwm: Manage owner assignment implicitly for drivers

Am Freitag, 4. August 2023, 16:27:06 CEST schrieb Uwe Kleine-König:

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.
