Can't this be merged in the previous patch?

Yes, my intention has been to keep other authors
patches fully documenting their effort.

So I cleaned and keep in logical chunks mine patches
and do only formating of others. But I am happy
to collapse these to into single one.

If the rest goes OK, then if the core and standalone
usable patches

  [PATCH 1/6] CAN bus simple SJA1000 PCI card emulation for QEMU
  [PATCH 2/6] CAN bus Kvaser PCI CAN-S (single SJA1000 channel) emulation added.

are accepted I prepare updated series.

If review leads to need update whole series, I merge
this to previous one before posting.

Thanks much for your time,

Pavel

I usually do that with the 'Signed-off-by'.

eg:
Signed-off-by: A
Fix the irq stuff
Signed-off-by: B

Not sure if this is the right way?
