serial: core: delete .set_wake() callback
This deletes the .set_wake() callback in the struct uart_ops. Apparently this has been unused since pre-git times. In the old-2.6-bkcvs it is deleted as part of a changeset removing the PM_SET_WAKEUP from pm_request_t which is since also deleted from the kernel. The apropriate way to set wakeups in the kernel is to have a code snippet like this in .suspend() or .runtime_suspend() callbacks: static int foo_suspend(struct device *dev) { if (device_may_wakeup(dev)) { /* Enable wakeups, set internal states */ } } This specific callback is not coming back.
