Russell King says: ==================== Rework SFP A2 access conditionals This series reworks the SFP A2 (diagnostics and control) access so we don't end up testing a variable number of conditions in several places. This also resolves a minor issue where we may have a module indicating that it is not SFF8472 compliant, doesn't implement A2, but fails to set the enhanced option byte to zero, leading to accesses to the A2 page that fail. The first patch adds a new flag "have_a2" which indicates whether we should be accessing the A2 page, and uses this for hwmon. The conditions are kept the same. The second patch extends the check for soft-state polling and control by using this "have_a2" flag (which effectively augments the check to include some level of SFF8472 compliance.) ==================== Link: https://lore.kernel.org/r/ZAoBnqGBnIZzLwpV@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
