The IPA driver remove callback, ipa_remove(), calls ipa_modem_stop() if the setup stage of initialization is complete. If a concurrent call to ipa_modem_start() or ipa_modem_stop() has begin but not completed, ipa_modem_stop() can return an error (-EBUSY). The next patch adds a driver shutdown callback, which will simply call ipa_remove(). We really want our shutdown callback to clean things up. So add a single retry to the ipa_modem_stop() call in ipa_remove() after a short (millisecond) delay. This offers no guarantee the shutdown will complete successfully, but we'll at least try a little harder before giving up.

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.
