This is a clean, well-justified single-patch fix. The commit message is thorough — it documents the call chain triggering the warning, explains why `DMA_ATTR_SKIP_CPU_SYNC` is appropriate, cites precedent from other exporters (`drm_gem_map_dma_buf`, `amdgpu_dma_buf_map`), and explains why the CPU sync is redundant given `begin_cpu_udmabuf`/`end_cpu_udmabuf` already handle explicit cache synchronization.
The fix is correct and minimal. The `Fixes:` tag and `Cc: stable` are appropriate since this is a regression fix for a real user-visible warning triggered during normal video playback.
**Verdict: Looks good.**
