If the rmnet_ipa0 network device has not been opened at the time we remove or shut down the IPA driver, its underlying TX and RX GSI channels will not have been started, and they will still be in ALLOCATED state. The RESET command on a channel is meant to return a channel to ALLOCATED state after it's been stopped. But if it was never started, its state will still be ALLOCATED, the RESET command is not required. Quietly skip doing the reset without printing an error message if a channel is already in ALLOCATED state when we request it be reset.

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.
