Subject: [PATCH 5.18 190/231] ASoC: codecs: rt700/rt711/rt711-sdca: initialize workqueues in probe

From: Pierre-Louis Bossart <pierre-louis.bossart@...ux.intel.com>

[ Upstream commit ba98d7d8b60ba410aa03834f6aa48fd3b2e68478 ]

The workqueues are initialized in the io_init functions, which isn't
quite right. In some tests, this leads to warnings throw from
__queue_delayed_work()

WARN_ON_FUNCTION_MISMATCH(timer->function, delayed_work_timer_fn);

Move all the initializations to the probe functions.
