If anyone has any objections, please let me know. ------------------ From: Renjiang Han [ Upstream commit e1c9adabb268cc5d56723b7df1da49e59070f309 ] get_framesize_raw_nv12() currently adds SZ_4K to the UV plane size and an additional SZ_8K to the total buffer size. This inflates the calculated sizeimage and leads userspace to over-allocate buffers without a clear requirement. Remove the extra SZ_4K/SZ_8K padding and compute the NV12 size as the sum of Y and UV planes, keeping the final ALIGN(size, SZ_4K) intact.
