Very minor nits, you can change this in a future add-on patch:

> +static DEVICE_ATTR(family, S_IRUGO, mic_show_family, NULL);

This should use DEVICE_ATTR_RO(), so that we don't have to audit the
permissions of your DEVICE_ATTR() files.

> +static DEVICE_ATTR(stepping, S_IRUGO, mic_show_stepping, NULL);

Same here.

> +static struct attribute *mic_default_attrs[] = {
> +	&dev_attr_family.attr,
> +	&dev_attr_stepping.attr,
> +
> +	NULL
> +};
> +
> +static struct attribute_group mic_attr_group = {
> +	.attrs = mic_default_attrs,
> +};
> +
> +static const struct attribute_group *__mic_attr_group[] = {
> +	&mic_attr_group,
> +	NULL
> +};

These last two structures can be replaced with:
ATTRIBUTE_GROUPS(mic_default);

> +void mic_sysfs_init(struct mic_device *mdev)
> +{
> +	mdev->attr_group = __mic_attr_group;
> +}

This is "odd", why not just export the data structure and reference it
in the other code?  The pci core does this, and so do other busses.

Anyway, it's not a big deal, just a bit strange to me.

thanks,
