Thanks for sending this PATCH in a friendly way. It's plain text and
seems to be well formatted, nice!
Two comments:
1) This patch does more than you say. You modify initialization and
reading. Please keep patch per change (and explain them).
2) You modify OpenWrt's copy of mainline driver code. I'm pretty sure
I explained it to you. I don't want these driver to start differ
again. I want to submit all change to mainline version and just copy
most recent version to bcm53xx. So instead of this patch against
OpenWrt's copy, please send a patch against mainline's nvram.c in the
first place.

I can see you switched to vmalloc. Just to confirm, I'm OK with either way.

One empty line will be enough.
