[Mesa-dev] [PATCH] st/va:Aligned image width and height to 16.

[Sharma, Deepak]

From: suresh guttula <suresh.guttula at amd.com>

In case of decoding of resolution like 40x24, while allocating surface
video buffer is always aligned with macroblock width/height which is 16. 
But when application tries to get data after decoding through vaCreateImage 
/vaGetImage, image width/height aligned with 2 and result a smaller image
buffer which causes the memory stomping issue.
