| Series | [hwc] platformdrmgeneric: get the gralloc usage directly from the handle | expand |
Hey Rob, I tested the patch on the imx6/etnaviv platform, and it all works. So I pushed the patch with t-b && r-b tags attached. Rob.

There's no point in using a gralloc perform() op to retrieve the usage as it is already stored in the handle like width, height, format, etc. So just copy it to the hwc_drm_bo_t and get it directly.
