Subject: [PATCH 0/9] ALSA: usb-audio: Support jack detection on Sony
 DualSense PS5

The Sony DualSense PS5 controller has an internal mono speaker, but it
also provides a 3.5mm jack socket for headphone output and headset
microphone input.

Since this is a UAC1 device, it doesn't advertise any jack detection
capability.  However, the controller is able to report HP & MIC insert
events via HID, i.e. through a dedicated input device managed by the
hid-playstation driver [1].

This patch series implements a quirk to create the jack controls for
headphone and headset mic, respectively, and registers an input handler
for each of them in order to intercept the related hotplug events.

It's worth noting there is no hard dependency on the HID patch set [1],
as the usb-audio driver will simply bind the jack controls to the input
devices when they become available - this is managed internally by the
input handler framework.

Unrelated to the above, the series also provides fixes to a bunch of
general coding style issues as reported by checkpatch.
