The ice driver uses an array of structures which link an info name with a function that formats the associated version data into a string. All existing format functions simply format already captured static data from the driver hw structure. Future changes will introduce format functions for reporting the versions of flash sections stored but not yet applied. This type of version data is not stored as a member of the hw structure. This is because (a) it might not yet exist in the case there is no pending flash update, and (b) even if it does, it might change such as if an update is canceled or replaced by a new update before finalizing. We could simply have each format function gather its own data upon being called. However, in some cases the raw binary version data is a combination of multiple different reported fields. Additionally, the current interface doesn't have a way for the function to indicate that the version doesn't exist. Refactor this function interface to take a new ice_info_ctx structure instead of the buffer pointer and length. This context structure allows for future extensions to pre-gather version data that is stored within the context struct instead of the hw struct. Allocate this context structure initially at the start of ice_devlink_info_get. We use dynamic allocation instead of a local stack variable in order to avoid using too much kernel stack once we extend it with additional data structures. Modify the main loop that drives the info reporting so that the version buffer string is always cleared between each format. Explicitly check that the format function actually filled in a version string of non-zero length. If the string is not provided, simply skip this version without reporting an error. This allows for introducing format functions of versions which may or may not be present, such as the version of a pending update that has not yet been activated.

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.
