While trying to get adapter fw-log for a function whose buffsize was set to 0, kernel panic occurred. When buffsize is 0, the kernel buffer for the log won't be allocated. When fw log usage was enabled, it failed to check the buffer size, and log usage was started. Eventually the driver referenced the unallocated log buffer. Added checks of the buffer size before allowing fw logging to be enabled and added check for valid buffer if enabling fw log. Performed a couple other minor cleanups while fixing this: - clarified log messages - re-evaluated log message severity - treat any error as an error, not only a couple codes Signed-off-by: Dick Kennedy <dick.kennedy@broadcom.com> Signed-off-by: James Smart <jsmart2021@gmail.com> Signed-off-by: Martin K.

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.
