[ 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.")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
