| |
Add Legacy PM OPS usage checks to bus_register() function. If Legacy PM OPS usage is found, print warning message to indicate that the driver code needs updating to use Dev PM OPS interfaces. This will help serve as a way to track drivers that still use Legacy PM OPS and fix them.
The Legacy PM OPS check looks for suspend(struct device *, pm_message_t) or resume(struct device *) bus level interfaces.
