Indentation could be off here (and a few more below), if it isn't my 
email client not displaying it properly.

This and others are technically okay but not what the commit message 
says. I'd say either split them into a separate patch or change the 
commit message to just say something like "Add device and client 
information to userq logging" so you give patch a wider mandate. ;)

My OCD is upset by inconsistencies of queue vs Queue and queue vs 
usermode queue vs user queue. Looks like a good opportunity to tidy 
things up while touching the lines.

Not really a kernel wide error if userspace passed invalid arguements to 
the ioctl. Usually it is good to avoid allowing userspace at will log 
spamming.
