commit 035b0fcf02707d3c9c2890dc1484b11aa5335eb1 upstream.
The driver uses an atomic_t variable: gs_usb:active_channels to keep
track of the number of opened channels in order to only allocate
memory for the URBs when this count changes from zero to one.
However, the driver does not decrement the counter when an error
occurs in gs_can_open(). This issue is fixed by changing the type from
atomic_t to u8 and by simplifying the logic accordingly.
It is safe to use an u8 here because the network stack big kernel lock
(a.k.a. rtnl_mutex) is being hold. For details, please refer to [1].

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.
