All,
This patch is pretty simple: It runs drivers/char/nvram.c through
Lindent, with a few manual cosmetics on top. I'm sending this now
because it makes my follow-up patch to this file easier :)
It is also available as a changeset from
http://suncobalt.bkbits.net/submit-2.4
2.5.x version coming seperately.
