regulator: hi6421: mark hi6421_regulator_ldo_get_optimum_mode() static
We get 1 warning when building kernel with W=1: drivers/regulator/hi6421-regulator.c:480:14: warning: no previous prototype for 'hi6421_regulator_ldo_get_optimum_mode' [-Wmissing-prototypes] In fact, this function is only used in the file in which it is declared and don't need a declaration, but can be made static. So this patch marks it 'static'. Signed-off-by: Baoyou Xie <baoyou.xie@linaro.org> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Mark Brown <broonie@kernel.org>
