Subject: soundwire: only handle alert events when the peripheral is attached
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=38cd651ebce7065a81c7e950d9e2ea1572304605;p=thirdparty%2Flinux.git

soundwire: only handle alert events when the peripheral is attached

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.
