At probing a UAC2/UAC3 device like NUX MG-300 USB interface, we get error messages "RANGE setting not yet supported". It comes the place where the driver tries to determine the resolution of mixer volumes via SET_CUR_RES and GET_CUR_RES verbs. Those verbs aren't supported on UAC2 and UAC3, hence the driver warns like the above. Although the driver handles this error and works as expected, it's still ugly to show such errors unnecessarily. This patch papers over the errors by applying the resolution detection only for UAC1 and skipping it for UAC2/UAC3.

README
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.
