Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
Nothing really major in here, just lots of constant development for new
hardware. Included in here are:
- Thunderbolt (i.e. USB4) fixes for reported issues and support for
new hardware types and devices
- USB typec additions of new drivers and cleanups for some existing
ones
- xhci cleanups and expanded tracing support and some platform
specific updates
- USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
and i2c drivers for that type of device (all acked by the respective
subsystem maintainers.)
- lots of USB gadget driver updates and cleanups
- new USB dwc3 platforms supported, as well as other dwc3 fixes and
cleanups
- USB chipidea driver updates
- other smaller driver cleanups and additions, full details in the
shortlog
All of these have been in the linux-next tree for a while with no
reported problems, EXCEPT for some merge conflicts that you will run
into in your tree. 2 of them are in device-tree files, which will be
trivial to resolve (accept both sides), and the last in the
drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
be pretty trivial (take the version in this branch), see here:
https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
for details, or I can provide a resolved merge point if needed.

This adjusts the point at which certain APIs will switch from

using a stack allocated buffer to a dynamically allocated buffer.

You shouldn't need to change this unless you really need to

optimize either stack space or performance. Change this carefully

since setting an incorrect value could cause stack corruption.
