Merge tag 'usb-6.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB / Thunderbolt updates from Greg KH:
"Here is the big set of USB and Thunderbolt driver changes for
6.17-rc1.

Lots of little things in here, mostly all small cleanups and updates,
no major new features this development cycle. Stuff included in here
is:

- xhci minor tweaks for error handling

- typec minor updates and a driver update

- gadget driver api cleanups

- unused function removals

- unbind memory leak fixes

- a few new device ids added

- a few new devices supported for some drivers

- other minor cleanups and changes

All of these have been in linux-next with no reported issues, with the
leak fixes being in the shortest amount of time, but they are
'obviously correct' :)"

 			- 0 when HPD’s logical state is low (HPD_Low) as defined by
 			     VESA DisplayPort Alt Mode on USB Type-C Standard.

+What:		/sys/bus/typec/devices/.../displayport/irq_hpd
+Date:		June 2025
+Contact:	RD Babiera <[e-mail]>
+Description:
+		IRQ_HPD events are sent over the USB PD protocol in Status Update and
+		Attention messages. IRQ_HPD can only be asserted when HPD is high,
+		and is asserted when an IRQ_HPD has been issued since the last Status
+		Update. This is a read only node that returns the number of IRQ events
+		raised in the driver's lifetime.

 The concepts described above translate to USB gadgets like this:
 
 1. A gadget has its config group, which has some attributes (idVendor,
-idProduct etc) and default sub-groups (configs, functions, strings).
-Writing to the attributes causes the information to be stored in
-appropriate locations. In the configs, functions and strings sub-groups

 2. The user creates configurations and functions, in the configurations
