If we encounter an error on i2c packet transmit, we won't have a valid flow anymore; since we didn't transmit a valid packet sequence, we'll have to wait for the key to timeout instead of dropping it on the reply. This causes the i2c lock to be held for longer than necessary. Instead, invalidate the flow on TX error, and release the i2c lock immediately.

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 reStructuredText 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.
