Collecting modem firmware traces is optional for the regular modem use. There are not many reasons for aborting device initialization due to an inability to initialize the trace port and (or) its debugfs interface. So, demote the initialization failure erro message into a warning and do not break the initialization sequence in this case. Rework packet processing and deinitialization so that they do not crash in case of uninitialized trace port. This change is mainly a preparation for an upcoming configuration option introduction that will help disable driver debugfs functionality.

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.
