commit 822fbd37410639acdae368ea55477ddd3498651d upstream.
When the try_module_get calls were removed from opening and closing of the
i2c debugfs file, the corresponding module_put calls were missed. This
results in an inaccurate module use count that requires a power cycle to
fix.
Fixes: 09fbca8e6240 ("IB/hfi1: No need to use try_module_get for debugfs")

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.
