w1: ds2482: make module parameter extra_config static
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? Signed-off-by: Colin Ian King <colin.king@canonical.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
