When flashing a new firmware image onto the device, the pldmfw library parses the image contents looking for a matching record. If no record can be found, the function reports an error of -ENOENT. This can produce a very confusing error message and experience for the user: $devlink dev flash pci/0000🆎00.0 file image.bin devlink answers: No such file or directory This is because the ENOENT error code is interpreted as a missing file or directory. The pldmfw library does not have direct access to the extack pointer as it is generic and non-netdevice specific. The only way that ENOENT is returned by the pldmfw library is when no record matches. Catch this specific error and report a suitable extended ack message: $devlink dev flash pci/0000🆎00.0 file image.bin Error: ice: Firmware image has no record matching this device devlink answers: No such file or directory In addition, ensure that we log an error message to the console whenever this function fails. Because our driver specific PLDM operation functions potentially set the extended ACK message, avoid overwriting this with a generic message. This change should result in an improved experience when attempting to flash an image that does not have a compatible record.

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.
