[2.6 patch] drivers/char/nvram.c: possible cleanups

[Adrian Bunk <bunk@stusta.de>]

This patch contains the following possible cleanups:
- make the needlessly global function __nvram_set_checksum static
- #if 0 the unused global function nvram_set_checksum
- remove the EXPORT_SYMBOL's for both functions

Signed-off-by: Adrian Bunk <bunk@stusta.de>
