ASoC: codecs: wsa88xx: fix codec initialisation
Merge series from Johan Hovold <johan@kernel.org>:
The soundwire update_status() callback may be called multiple times with
the same ATTACHED status but initialisation should only be done when
transitioning from UNATTACHED to ATTACHED.
This series fixes the Qualcomm wsa88xx codec drivers that do unnecessary
reinitialisation or potentially fail to initialise at all.
Included is also a related clean up suppressing a related codec variant
printk.
