367 * dump requests, ->cleanup() is called for each message.
368 * @set_validate:
369 * Check if set operation is supported for a given device, and perform
370 * extra input checks. Expected return values:
371 * - 0 if the operation is a noop for the device (rare)
372 * - 1 if operation should proceed to calling @set
