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,

Two different files, with the same name? You are asking for trouble in
the future, getting them confused :)
Again, very minor fixups for later (I can even do them...)
+static DEVICE_ATTR(state, S_IRUGO|S_IWUSR, mic_show_state, mic_store_state);
DEVICE_ATTR_RW() please.
Same for the other attributes you create in this patch.
thanks,
