The messages are redundant since 'check_fb_gem_memory_type' already prints out exactly the same string when it fails.

Hi,

While the VP (video processor) supports arbitrary scaling of its input, the mixer just supports a simple 2x (line doubling) scaling. Expose this functionality and exit early when an unsupported scaling configuration is encountered.

This was tested with modetest's DRM plane test (from the libdrm test suite) on an Odroid-X2 (Exynos4412).

v2: Put if- and return-statement on different lines.

With this changes, i got errors when crtc gets out bound of actual screen area. I sent patch to fix it and to calculate ratio from exynos_drm plane codes.
