sysfs, driver-core: remove unused {sysfs|device}_schedule_callback_owner()
All device_schedule_callback_owner() users are converted to use device_remove_file_self(). Remove now unused {sysfs|device}_schedule_callback_owner(). Signed-off-by: Tejun Heo <tj@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

619 * device_schedule_callback_owner - helper to schedule a callback for a device
620 * @dev: device.
621 * @func: callback function to invoke later.
622 * @owner: module owning the callback routine
623 *
624 * Attribute methods must not unregister themselves or their parent device
625 * (which would amount to the same thing). Attempts to do so will deadlock,
626 * since unregistration is mutually exclusive with driver callbacks.
627 *
628 * Instead methods can call this routine, which will attempt to allocate
629 * and schedule a workqueue request to call back @func with @dev as its
630 * argument in the workqueue's process context. @dev will be pinned until
631 * @func returns.
632 *
633 * This routine is usually called via the inline device_schedule_callback(),
634 * which automatically sets @owner to THIS_MODULE.
635 *
636 * Returns 0 if the request was submitted, -ENOMEM if storage could not
637 * be allocated, -ENODEV if a reference to @owner isn't available.
638 *
639 * NOTE: This routine won't work if CONFIG_SYSFS isn't set! It uses an
640 * underlying sysfs routine (since it is intended for use by attribute
641 * methods), and if sysfs isn't available you'll get nothing but -ENOSYS.
