The firmware can only be patched once. The current code checks if the firmware supports the features required by the driver and then patches if it does not. This could lead to the device being patched twice if the device was patched before the driver took control, but with a firmware that doesn't support the features the driver requires. This would fail but potentially in unpredictable ways. The check should actually check the device is at the ROM version, and patch the device if it is. Then a separate later check should error out if the devices firmware is still too old to be supported. This will at least fail in a clean way with a nice error message.

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.
