Subject: drm/tegra: Cleanup header file
X-Git-Tag: v4.9.8~6258^2~9^2~46
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=688c59afbf74cf729d4f50b0cd862bb30f6de658;p=platform%2Fkernel%2Flinux-rpi3.git

drm/tegra: Cleanup header file

Remove extern keyword from function prototypes since it isn't needed and
drop an unnecessary forward declaration.
