Patch Review

**Status: Looks good, minor note**

The helper is clean and correct:
```c
static inline bool
drm_dp_lane_count_is_valid(int lane_count)
{
	return lane_count == 1 || lane_count == 2 || lane_count == 4;
}
```

This correctly reflects the DP spec (1, 2, or 4 lanes only). Using a `static inline` in the header is appropriate for such a trivial function.

One minor observation: there's no `drm_dp_lane_count_is_valid` user beyond this series. It might be worth mentioning in the commit message that other drivers could adopt it to replace ad-hoc checks, but that's a commit message nit, not a code issue.
