Many of these could use a colon after the %s used with __func__
to make the output more consistent with other modules.

nit: for VFIO platform devices vdev->name and dev_name(dev) are the
same. But for amba devices they are different I think so it looks
sensible to keep both names at the moment.

OK, I'll keep this hunk as-is.

Thanks, Joe. I added a colon to the two in
vfio_platform_amdxgbe_reset(). Those were the only ones I saw, except
for a couple "%s failed" messages in
drivers/vfio/vfio_iommu_spapr_tce.c, which I didn't change because (1)
they can't use dev_err() so slightly out of scope for this patch, and
(2) it arguably reads more naturally without the colon.
In vfio_pci.c, I converted some pr_info() to dev_info() without adding
a dev_fmt definition, so that removed the KBUILD_MODNAME prefix, which
I didn't intend. I'll add "#define dev_fmt pr_fmt" to restore the
prefix.
Messages from drivers/vfio use a variety of prefixes (none, "VFIO: ",
KBUILD_MODNAME, __func__). That could potentially be rationalized but
I would want Alex's guidance first.

Hmm, sort of hard to generalize. I suspect "VFIO:" is not super
useful, the module name is probably a better choice, augmented by
__func__ where it adds useful context. That's probably the approach
I'd take. Thanks,
Alex
