[ Upstream commit11b5c101e2] The `max3421_hub_control()` function handles USB hub class requests to the virtual root hub. The `GetPortStatus` case correctly rejects requests with `index != 1`, since the virtual root hub has only a single port. However, the `ClearPortFeature` and `SetPortFeature` cases lack the same check. Fix this by extending the `index != 1` rejection to both cases, matching the existing behavior of `GetPortStatus`. Fixes:2d53139f31("Add support for using a MAX3421E chip as a host driver.")
