When executing suspend to ram, if lacking the operations to reset device and free unused buffers before deleting a vq, resource leaks and inconsistent device status will appear. According to chapter "3.3.1 Driver Requirements: Device Cleanup:" of virtio-specification: Driver MUST ensure a virtqueue isn’t live (by device reset) before removing exposed buffers. Therefore, modify the virtinput_freeze function to reset the device and delete the unused buffers before deleting the virtqueue, just like virtinput_remove does.

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 reStructuredText 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.
