Hello, everyone. I just thought I should share very minor nitpicks
I have found over time in the kernel code. Most of them I have 
already posted in one way or another. They are

1. Tabs vs spaces in wsmux.c.
2. Extra defines (to the best of my knowledge) in wsdisplayvar.h.
3. Unnecessary variable, in my opinion in wsdisplay.c.
4. Tabs vs spaces in apm.c
And finally, if you would be so kind,
5. Added device id in usbdevs (I know this doesn't make bluetooth
work, just nice to have it identified). Also please see
https://marc.info/?l=openbsd-ppc&m=166128113030121&w=2

All the best, patches follow.
