Subject: Remove choose_drm_modifier
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=336a6bdc9d36330144a7ec1e9f1a900acd4496ac;p=android-x86%2Fexternal-IA-Hardware-Composer.git

Remove choose_drm_modifier

We should not relay on a simple util functions to choose CCS
modificators. That could be risky if one drm plane does not support
CCS modificator. We should let drmplane tell us which kind of modifier
the plane preferred
