[PATCH] drm/exynos: remove unused variables

[Arnd Bergmann]

After a recent change, two variables were left unused:

exynos/exynos5433_drm_decon.c: In function 'decon_enable':
exynos/exynos5433_drm_decon.c:381:6: warning: unused variable 'i' 
[-Wunused-variable]
exynos/exynos5433_drm_decon.c:380:6: warning: unused variable 'ret' 
[-Wunused-variable]

This removes them too.
