The 'w' argument to NVCopyNV12ColorPlanes is used to index into the source image. line_len is rounded up to 8 on NV50+, so if the source image (+ left offset) is not rounded to 8, NVCopyNV12ColorPlanes could read past the end of the array and crash X. This change can cause the last few horizontal pixels of dst to not be initialized, but they should be truncated by the renderer anyways.

This avoids a false-positive in the clang static analyzer, it can't know that !y and x are mutually exclusive. The result looks something like this: if (y) { ... } else { ppix = ... if (x) {
