Subject: [PATCH] regulator: hi6421: mark hi6421_regulator_ldo_get_optimum_mode() static
Date: Wed, 31 Aug 2016 17:30:31 +0800	[thread overview]
Message-ID: <1472635831-20290-1-git-send-email-baoyou.xie@linaro.org> (raw)

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'.
