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().

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