Subject: [PATCH 1/4] soundwire: stream: Add missing clear of alloc_slave_rt
Date:   Thu, 1 Jun 2023 17:16:19 +0100

The current path that skips allocating the slave runtime does not clear
the alloc_slave_rt flag, this is clearly incorrect. Add the missing
clear, so the runtime won't be erroneously cleaned up.
