Subash Abhinov Kasiviswanathan 64e86fec54 net: qualcomm: rmnet: Fix warning seen with fill_info 
When the last rmnet device attached to a real device is removed, the
real device is unregistered from rmnet. As a result, the real device
lookup fails resulting in a warning when the fill_info handler is
called as part of the rmnet device unregistration.

Fix this by returning the rmnet flags as 0 when no real device is
present.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
