These Mini-Box LCDs are using Microchip components and sub-licensed product
IDs. Whilst here, update the constant names and descriptions for the products
to use the names listed on the manufacturer's website rather than vague ones.
The picoLCD 4x20 is named that on the manufacturer's website so prefer that
name, even though linux-usb.org lists it with the numbers reversed as one might
expect.

Some USB WLAN devices have "on-board" storage showing up as umass
and making the root mount wait for a very long time.
The WLAN drivers know how to deal with that an issue an eject
command later when attaching themselves.
Introduce a quirk to not probe these devices as umass and avoid
hangs and confusion altogether.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
mutexes or using any callouts when active.
Trying to lock a mutex when KDB is active or the scheduler is stopped
can result in infinite wait loops. The same goes for calling callout
related functions which in turn lock mutexes.
If the USB controller at which a USB keyboard is connected is idle
when KDB is entered, polling the USB keyboard via USB will always
succeed. Else polling may fail depending on which state the USB
subsystem and USB interrupt handler is in. This is unavoidable unless
KDB can wait for USB interrupt threads to complete before stalling the
CPU(s).
