Subject: ASoC: arizona: Remove redundant extern declarations
X-Git-Tag: v4.10-rc1~121^2~3^2~13^3~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=739507159e4e135a0a21df5a947753f44b0789b8;p=platform%2Fkernel%2Flinux-exynos.git

ASoC: arizona: Remove redundant extern declarations

Functions are given external linkage by default making the extern's
unnecessary, as such remove them.
