In gsi_channel_update(), a reference count is taken on the last completed transaction "to keep it from completing" before we give the event back to the hardware. Completion processing for that transaction (and any other "new" ones) will not occur until after this function returns, so there's no risk it completing early. So there's no need to take and drop the additional transaction reference. Use local variables in the call to gsi_evt_ring_doorbell().

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.
