+Subject: drm/amdgpu: fix division by zero with invalid uvd dimensions
+
+From: Boyuan Zhang <boyuan.zhang@amd.com>
+
+commit 0c01c811be47e6b146552dd59bfedbea8f09b8f4 upstream.
+
+When width or height is less than 16, width_in_mb or height_in_mb
+becomes 0, leading to fs_in_mb being 0. This causes a division by
+zero when calculating num_dpb_buffer in H264 and H264 Perf decode
+paths.
+
+Add validation to reject frames with width < 16 or height < 16
+before performing any calculations that depend on these values.
+
+V2: Format change - move up all vaiable definitions.
+V3: Use warn_once to avoid spam.
