ALSA: usb-audio: Disable Lenovo P620 Rear line-in volume control
The USB device (0x17aa:0x1046) that support Lenovo P620 rear panel line-in claim to support volume control, but it doens't seem to have an AMP, so when line-in volume lowers below 80, nothing gets recorded anymore. Disable the volume control to workaround the issue.

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.
