This is a single-patch series that adds error checking to the `drm_dp_dpcd_read()` call in `intel_edp_set_sink_rates()`. The motivation is reasonable — the existing code reads DPCD supported link rates into a stack-allocated array and parses it unconditionally, which could use uninitialized stack data if the read fails or is short. The fix approach is sensible: check the return value and fall back to default rate handling on failure.
However, the patch has a notable mismatch with the current upstream code and some minor issues worth addressing.
**Verdict**: Reasonable defensive fix with minor issues. Needs a small update to match the current kernel tree.
