Subject: [PATCH] w1: ds2482: make module parameter extra_config static

From: Colin Ian King <colin.king@...onical.com>

The variable extra_config is local to the source and does not
need to be in global scope, so make it static.

Cleans up sparse warning:
warning: symbol 'extra_config' was not declared. Should it be static?
