Author: Gwan-gyeong Mun <[email protected]> Date: Sun Nov 20 20:44:22 2016 +0900 anv: Fix unintentional integer overflow in anv_CreateDmaBufImageINTEL Since both pCreateInfo->strideInBytes and pCreateInfo->extent.height are of uint32_t type 32-bit arithmetic will be used. Fix unintentional integer overflow by casting to uint64_t before multifying.
