[ Upstream commitecdc28defc] If the network devices connected to the system beyond HSO_MAX_NET_DEVICES. add_net_device() in hso_create_net_device() will be failed for the network_table is full. It will lead to business failure which rely on network_table, for example, hso_suspend() and hso_resume(). It will also lead to memory leak because resource release process can not search the hso_device object from network_table in hso_free_interface(). Add failure handler for add_net_device() in hso_create_net_device() to solve the above problems.

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.
