I would remove the printk:
- it is the only email on my dmesg, along two other copyright
notices (Ingo and Intel). So it seems that the dmesg clean-up
is going on.
- the code of driver is stable, and now it is updated only in
kernel trees, so IMO it is better to use kernel version on
bug report. BTW I don't think people will update the version
number of driver.
- IMO it is enough to printk the microcode loads, not the
driver load.
