From e5cf84e8224c49f335aec6b69b3e373bbbe4641a Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sat, 12 Aug 2017 22:34:03 +0100 Subject: w1: ds2438: make several functions static The functions w1_ds2438_get_page, w1_ds2438_get_temperature, w1_ds2438_change_config_bit and w1_ds2438_get_voltage are local to the source and do not need to be in global scope, so make it static. Cleans up sparse warnings: symbol 'w1_ds2438_get_page' was not declared. Should it be static? symbol 'w1_ds2438_get_temperature' was not declared. Should it be static? symbol 'w1_ds2438_change_config_bit' was not declared. Should it be static? symbol 'w1_ds2438_get_voltage' was not declared. Should it be static?
