Subject: [PATCH] drm/exynos: remove unused variables

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.

Signed-off-by: Arnd Bergmann <arnd@...db.de>
Fixes: 186ba87a6e31 ("drm/exynos: add pm_runtime to DECON 5433")
