If anyone has any objections, please let me know. ------------------ From: Bard Liao [ Upstream commit 38cd651ebce7065a81c7e950d9e2ea1572304605 ] It doesn't make sense to handle an alert event when the peripheral is not attached. The slave->status could be SDW_SLAVE_ATTACHED or SDW_SLAVE_ALERT when it is attached on the bus.
