[PATCH] drm/rockchip: Fix build warning in analogix_dp-rockchip.c

[Sean Paul]

I didn't catch this before applying, just right after (of course).

Fixes:
../drivers/gpu/drm/rockchip/analogix_dp-rockchip.c: In function
‘rockchip_dp_of_probe’:
../drivers/gpu/drm/rockchip/analogix_dp-rockchip.c:276:6: warning:
unused variable ‘ret’ [-Wunused-variable]
  int ret;
        ^~~

Fixes: 102712a32ff5 ("drm/rockchip: analogix_dp: Remove unnecessary init
code")
