[PATCH 0/1][SRU][OEM-5.13/OEM-5.14] Fix missing external headset after resume problem for Cirrus CS8409 sound driver

[Chris Chiu]

BugLink: https://bugs.launchpad.net/bugs/1952385

[Impact]
On some platforms with Cirrus CS8409 audio codec, the external headset will fail to be detected after system resume.

[Fix]
Cirrus released a fix and send it upstream for approval. It's trying to schedule a harmless delayed work to do jack detection to reflect the real power state after resume.

[Test]
Plug-in an external headset in front headset port, suspend/resume the system then check whether the headset function works as expected.

[Where problem could occur]
Low. It only affect the platforms with Cirrus codec CS8409 which used to have problem.
