3.5-stable review patch. If anyone has any objections, please let me know.
------------------
From: Mark Brown <broo...@opensource.wolfsonmicro.com>
commit eb4d5fc1f0ce89e3d5b072c594a1e213a0e05881 upstream.
In some circumstances we may need to flush volume updates to the device
after switching to class W mode. Do this unconditionally to ensure that
these situations are handled.
