patches
This series add support for the cs42l44 to the cs42l43 driver.
I have based these patches on the series by Uwe from here:
https://lore.kernel.org/lkml/cover.1783507945.git.u.kleine-koenig@baylibre.com/
Since they both touch the device id arrays, does mean Uwe's series will
need to be merged before these but probably simpler this way round as
his series is a lot bigger.
Thanks,
Charles
