Hi all,

I have added support for controlling the (way too bright) XG mobile
LEDs in hid-asus and added the i2c version of already supported
hardware that was probed only when it's a USB: these are two separate
features changes and are the only two that are not fixes for
pre-existing issue (see below).

Auto-review bot has spotted a bunch of pre-existing problems alongside
problems in my own code therefore at this point I am going to fix the
more problems I can and including those fixes and improvements in this
patchset.

For v4 I decided to follow Antheas' suggestion of reusing the existing
workqueue and by making it more generic I solved a good bunch of issues.

The v5 iteration is simply me fixing a bunch of bugs in new code spotted
by the bot. Thanks for providing such a useful tool!

On a side node this patchset has a few more warnings: specifically
"WARNING: Prefer kzalloc_obj over kzalloc with sizeof" but it's a false
positive as that would introduce sleeping calls in atomic contexts.
