Subject: [PATCH 2/2] ASoC: wcd934x: fix order of Slimbus unprepare/disable
Date:   Wed, 21 Sep 2022 16:53:54 +0200

Slimbus streams are first prepared and then enabled, so the cleanup path
should reverse it.  The unprepare sets stream->num_ports to 0 and frees
the stream->ports.  Calling disable after unprepare was not really
effective (channels was not deactivated) and could lead to further
issues due to making transfers on unprepared stream.
